Class SimplexSolver.EnterInfo

java.lang.Object

org.ojalgo.optimisation.linear.SimplexSolver.EnterInfo

Enclosing class:

SimplexSolver

static final class SimplexSolver.EnterInfo
extends Object

Enter to SimplexStore.ColumnState.BASIS from either SimplexStore.ColumnState.LOWER, SimplexStore.ColumnState.UPPER, or SimplexStore.ColumnState.UNBOUNDED.

In case of a bound-switch nothing enters the basis. In such case this type declares "the switch" rather than the enter-part of a normal basis-update.
