Description copied from interface: GLPSolver

Solve General Linear Programing Problem (variables are allowed to be negative) by optimizing the 'objective' function under given 'constraints'.

Specified by:

solve in interface GLPSolver

Parameters:

direction - optimization direction

objective - coefficients of the objective function

constraints - constraints

Returns:

the result of optimization

Throws:

UnboundedSystemException - when constraint system is unbounded and solution cannot be found
