Detailed Description

Solver Class

A solver represents the main computation engine. It implements the entire
range of Constraint Programming protocols:

• Reversibility
  
• Propagation
  
• Search
  
  Usually, Constraint Programming code consists of
  
• the creation of the Solver,
  
• the creation of the decision variables of the model,
  
• the creation of the constraints of the model and their addition to the
  solver() through the AddConstraint() method,
  
• the creation of the main DecisionBuilder class,
  
• the launch of the solve() method with the decision builder.
  
  For the time being, Solver is neither MT_SAFE nor MT_HOT.

addCastConstraint()

void com.google.ortools.constraintsolver.Solver.addCastConstraint	(	CastConstraint	constraint,
		IntVar	target_var,
		IntExpr	expr )

Adds 'constraint' to the solver and marks it as a cast constraint, that
is, a constraint created calling Var() on an expression. This is used
internally.

Definition at line 386 of file Solver.java.

addConstraint()

void com.google.ortools.constraintsolver.Solver.addConstraint

(

Constraint

c

)

Adds the constraint 'c' to the model.

After calling this method, and until there is a backtrack that undoes the
addition, any assignment of variables to values must satisfy the given
constraint in order to be considered feasible. There are two fairly
different use cases:

• the most common use case is modeling: the given constraint is really
  part of the problem that the user is trying to solve. In this use case,
  AddConstraint is called outside of search (i.e., with state() ==
OUTSIDE_SEARCH). Most users should only use AddConstraint in this
  way. In this case, the constraint will belong to the model forever: it
  cannot be removed by backtracking.
  
  
• a rarer use case is that 'c' is not a real constraint of the model. It
  may be a constraint generated by a branching decision (a constraint whose
  goal is to restrict the search space), a symmetry breaking constraint (a
  constraint that does restrict the search space, but in a way that cannot
  have an impact on the quality of the solutions in the subtree), or an
  inferred constraint that, while having no semantic value to the model (it
  does not restrict the set of solutions), is worth having because we
  believe it may strengthen the propagation. In these cases, it happens
  that the constraint is added during the search (i.e., with state() ==
  IN_SEARCH or state() == IN_ROOT_NODE). When a constraint is
  added during a search, it applies only to the subtree of the search tree
  rooted at the current node, and will be automatically removed by
  backtracking.
  
  This method does not take ownership of the constraint. If the constraint
  has been created by any factory method (Solver::MakeXXX), it will
  automatically be deleted. However, power users who implement their own
  constraints should do: solver.AddConstraint(solver.RevAlloc(new<br> MyConstraint(...));

concatenateOperators() [1/3]

LocalSearchOperator com.google.ortools.constraintsolver.Solver.concatenateOperators

(

LocalSearchOperator[]

ops

)

Creates a local search operator which concatenates a vector of operators.
Each operator from the vector is called sequentially. By default, when a
neighbor is found the neighborhood exploration restarts from the last
active operator (the one which produced the neighbor).
This can be overridden by setting restart to true to force the exploration
to start from the first operator in the vector.

The default behavior can also be overridden using an evaluation callback
to set the order in which the operators are explored (the callback is
called in LocalSearchOperator::Start()). The first argument of the
callback is the index of the operator which produced the last move, the
second argument is the index of the operator to be evaluated. Ownership of
the callback is taken by ConcatenateOperators.

Example:

const int kPriorities = {10, 100, 10, 0};
int64_t Evaluate(int active_operator, int current_operator) {
return kPriorities[current_operator];
}

LocalSearchOperator* concat =
solver.ConcatenateOperators(operators,
NewPermanentCallback(&Evaluate));

The elements of the vector operators will be sorted by increasing priority
and explored in that order (tie-breaks are handled by keeping the relative
operator order in the vector). This would result in the following order:
operators[3], operators[0], operators[2], operators[1].

makeIntervalRelaxedMax()

IntervalVar com.google.ortools.constraintsolver.Solver.makeIntervalRelaxedMax

(

IntervalVar

)

Creates and returns an interval variable that wraps around the given one,
relaxing the max start and end. Relaxing means making unbounded when
optional. If the variable is non optional, this method returns
interval_var.

More precisely, such an interval variable behaves as follows:
When the underlying must be performed, the returned interval variable
behaves exactly as the underlying;
When the underlying may or may not be performed, the returned interval
variable behaves like the underlying, except that it is unbounded on
the max side;
When the underlying cannot be performed, the returned interval variable
is of duration 0 and must be performed in an interval unbounded on
both sides.

This is very useful for implementing propagators that may only modify
the start min or end min.

makeLocalSearchPhase() [1/4]

DecisionBuilder com.google.ortools.constraintsolver.Solver.makeLocalSearchPhase	(	Assignment	assignment,
		LocalSearchPhaseParameters	parameters )

Local Search decision builders factories.
Local search is used to improve a given solution. This initial solution
can be specified either by an Assignment or by a DecisionBulder, and the
corresponding variables, the initial solution being the first solution
found by the DecisionBuilder.
The LocalSearchPhaseParameters parameter holds the actual definition of
the local search phase:

• a local search operator used to explore the neighborhood of the current
  solution,
  
• a decision builder to instantiate unbound variables once a neighbor has
  been defined; in the case of LNS-based operators instantiates fragment
  variables; search monitors can be added to this sub-search by wrapping
  the decision builder with MakeSolveOnce.
  
• a search limit specifying how long local search looks for neighbors
  before accepting one; the last neighbor is always taken and in the case
  of a greedy search, this corresponds to the best local neighbor;
  first-accept (which is the default behavior) can be modeled using a
  solution found limit of 1,
  
• a vector of local search filters used to speed up the search by pruning
  unfeasible neighbors.
  Metaheuristics can be added by defining specialized search monitors;
  currently down/up-hill climbing is available through OptimizeVar, as well
  as Guided Local Search, Tabu Search and Simulated Annealing.

Creates a constraint which accumulates values along a path such that:
cumuls[next[i]] = cumuls[i] + transit_evaluator(i, next[i]).
Active variables indicate if the corresponding next variable is active;
this could be useful to model unperformed nodes in a routing problem.
Ownership of transit_evaluator is taken and it must be a repeatable
callback.

makeSortingConstraint()

Constraint com.google.ortools.constraintsolver.Solver.makeSortingConstraint	(	IntVar[]	vars,

Creates a constraint binding the arrays of variables "vars" and
"sorted_vars": sorted_vars[0] must be equal to the minimum of all
variables in vars, and so on: the value of sorted_vars[i] must be
equal to the i-th value of variables invars.

This constraint propagates in both directions: from "vars" to
"sorted_vars" and vice-versa.

Behind the scenes, this constraint maintains that:

• sorted is always increasing.
  
• whatever the values of vars, there exists a permutation that
  injects its values into the sorted variables.

MetaHeuristics which try to get the search out of local optima.
Creates a Tabu Search monitor.
In the context of local search the behavior is similar to MakeOptimize(),
creating an objective in a given sense. The behavior differs once a local
optimum is reached: thereafter solutions which degrade the value of the
objective are allowed if they are not "tabu". A solution is "tabu" if it
doesn't respect the following rules:

• improving the best solution found so far
  
• variables in the "keep" list must keep their value, variables in the
  "forbid" list must not take the value they have in the list.
  Variables with new values enter the tabu lists after each new solution
  found and leave the lists after a given number of iterations (called
  tenure). Only the variables passed to the method can enter the lists.
  The tabu criterion is softened by the tabu factor which gives the number
  of "tabu" violations which is tolerated; a factor of 1 means no violations
  allowed; a factor of 0 means all violations are allowed.

solve() [6/6]

boolean com.google.ortools.constraintsolver.Solver.solve	(	DecisionBuilder	db,
		SearchMonitor[]	monitors )

Solves the problem using the given DecisionBuilder and returns true if a
solution was found and accepted.

These methods are the ones most users should use to search for a solution.
Note that the definition of 'solution' is subtle. A solution here is
defined as a leaf of the search tree with respect to the given decision
builder for which there is no failure. What this means is that, contrary
to intuition, a solution may not have all variables of the model bound.
It is the responsibility of the decision builder to keep returning
decisions until all variables are indeed bound. The most extreme
counterexample is calling Solve with a trivial decision builder whose
Next() method always returns nullptr. In this case, Solve immediately
returns 'true', since not assigning any variable to any value is a
solution, unless the root node propagation discovers that the model is
infeasible.

This function must be called either from outside of search,
or from within the Next() method of a decision builder.

Solve will terminate whenever any of the following event arise:
A search monitor asks the solver to terminate the search by calling
solver()->FinishCurrentSearch().
A solution is found that is accepted by all search monitors, and none of
the search monitors decides to search for another one.

Upon search termination, there will be a series of backtracks all the way
to the top level. This means that a user cannot expect to inspect the
solution by querying variables after a call to Solve(): all the
information will be lost. In order to do something with the solution, the
user must either:

Use a search monitor that can process such a leaf. See, in particular,
the SolutionCollector class.
Do not use Solve. Instead, use the more fine-grained approach using
methods NewSearch(...), NextSolution(), and EndSearch().

Parameters

db	The decision builder that will generate the search tree.
monitors	A vector of search monitors that will be notified of various events during the search. In their reaction to these events, such monitors may influence the search.

The difference between a SolveAndCommit() and a Solve() method
call is the fact that SolveAndCommit will not backtrack all
modifications at the end of the search. This method is only
usable during the Next() method of a decision builder.

tryDecisions() [1/4]

DecisionBuilder com.google.ortools.constraintsolver.Solver.tryDecisions	(	DecisionBuilder	db1,
		DecisionBuilder	db2 )

Creates a decision builder which will create a search tree where each
decision builder is called from the top of the search tree. For instance
the decision builder Try(db1, db2) will entirely explore the search tree
of db1 then the one of db2, resulting in the following search tree:
Tree root |
\ |
db1 tree db2 tree |

This is very handy to try a decision builder which partially explores the
search space and if it fails to try another decision builder.

"Try"-builders "recursively". For instance, Try(a,b,c,d) will give a tree
unbalanced to the right, whereas Try(Try(a,b), Try(b,c)) will give a
balanced tree. Investigate if we should only provide the binary version
and/or if we should balance automatically.

EvaluatorStrategy.

This enum is used by Solver::MakePhase to specify how to select variables
and values during the search.
In Solver::MakePhase(const std::vector<IntVar*>&, IntVarStrategy,
IntValueStrategy), variables are selected first, and then the associated
value.
In Solver::MakePhase(const std::vector<IntVar*>& vars, IndexEvaluator2,
EvaluatorStrategy), the selection is done scanning every pair
<variable, possible value>. The next selected pair is then the best among
all possibilities, i.e. the pair with the smallest evaluation.
As this is costly, two options are offered: static or dynamic evaluation. Pairs are compared at the first call of the selector, and results are
cached. Next calls to the selector use the previous computation, and so
are not up-to-date, e.g. some <variable, value> pairs may not be
possible anymore due to propagation since the first to call.
