Class NewGLPKSolver

java.lang.Object

org.simulator.fba.NewGLPKSolver

All Implemented Interfaces:

scpsolver.lpsolver.LinearProgramSolver

public class NewGLPKSolver
extends Object
implements scpsolver.lpsolver.LinearProgramSolver

Class for solving the linear programs.

This class is added temporarily till issue of freeing the memory of the instance of the GlpkSolver in the solve() method gets resolved in SCPSolver.

Currently, while running the SBML Test Suite, it crashes in between due to the memory allocation error for GlpkSolver class.

The error: glp_free: memory allocation error Error detected in file env/alloc.c at line 72

This happened as the memory of the GlpkSolver instance was not freed. So, this class is the copy of the GLPKSolver class from the SCPSolver. The only change here is that the `solver.deleteProb();` is called in the solve() method after its use is done which deletes the object, i.e., frees the memory.

This class will be removed from SBSCL as this issue gets resolved in the SCPSolver.
