◆ exact_zeros

bool operations_research::math_opt::LpModelSolveParametersTestParameters::exact_zeros

If true, we EXPECT that the solver to return a value of exactly 0.0 for decisions variables >= 0 that take zero at the optimum on a very small problem. In general, simplex solvers are more likely to do this, but very few solvers actually guarantee this. All tests relying on this behavior are brittle and we should try to eliminate them.
