Class LSBBExpression

java.lang.Object

localsolverblackbox.LSBBExpression

public class LSBBExpression
extends java.lang.Object

Mathematical modeling expression. Expressions are used to build the mathematical optimization model associated to LocalSolverBlackBox. An expression is composed of an operator (which corresponds to its type) and its operands (which are other expressions of the model).
