Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	LinearSolver.Builder Deprecated. v50 Use LinearSolver.StandardBuilder instead
static class	LinearSolver.GeneralBuilder Compared to LinearSolver.StandardBuilder this builder: 1) Accepts inequality constraints 2) Has relaxed the requiremnt on the RHS to be non-negative (both equalities and inequalities) Compared to ConvexSolver.Builder this builder: 1) Requires the objective function to be linear (or only the linear factors will be concidered) 2) Assumes (requires) variables to be non-negative
static class	LinearSolver.ModelIntegration
static class	LinearSolver.StandardBuilder Defines optimisation problems on the (LP standard) form:
