Enum MPModelRequest.SolverType

java.lang.Object
java.lang.Enum<MPModelRequest.SolverType>
com.google.ortools.linearsolver.MPModelRequest.SolverType
All Implemented Interfaces:
com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, Serializable, Comparable<MPModelRequest.SolverType>, java.lang.constant.Constable
Enclosing class:
MPModelRequest
public static enum MPModelRequest.SolverType extends Enum<MPModelRequest.SolverType> implements com.google.protobuf.ProtocolMessageEnum
 The solver type, which will select a specific implementation, and will also
 impact the interpretation of the model (i.e. are we solving the problem
 as a mixed integer program or are we relaxing it as a continuous linear
 program?).
 This must remain consistent with MPSolver::OptimizationProblemType.
