Package org.ssclab.pl.milp

This package contains classes for solving linear programming problems. The LP class allows solving problems with continuous variables, whereas the MILP class also allows solving problems involving integer and semicontinuous variables. The LP class utilizes the simplex algorithm, while the MILP class employs the Branch and Bound method. SSC Software www.sscLab.org

Interface Summary

Interface	Description
FormatTypeInput
Solution	This interface allows accessing the values taken by the n variables of the optimal solution.
SolutionConstraint	* This interface allows accessing a constraint of the LP problem where each unknown variable has been assigned the optimal value.
Variable	This interface allows accessing the optimal value assumed by the j-th variable of the LP problem (j=1..N).

Class Summary

Class	Description
Constraint	This class allows you to build objects, each of which represents a constraint for a linear programming problem expressed in matrix notation
LinearObjectiveFunction	This class allows instantiating objects representing the objective function in linear programming problems expressed in matrix notation.
ListConstraints
LP	This class allows executing and solving formulations of linear programming problems.
MILP	This class allows executing and solving formulations of mixed integer linear programming problems, binary or semicontinuous.

Enum Summary

Enum	Description
ConsType	Enumeration used to define the type of relationship in a Constraint object.
EPSILON	Enumeration for epsilon values ranging from 1E-16 to 1E-4.
FormatTypeInput.FormatType
GoalType	This enumeration allows declaring the type of optimization sought on the objective function: maximization or minimization.
SolutionType	This enumeration defines the different types of results that the two-phase method returns.
Variable.TYPE_VAR	Defines the type of variable: integer, binary, or real.
