The parameter len is the number of elements of ind and val which will be socumentation, and must be smaller or equal to the length of both vectors; in Julia it is optional and the ind and val must have the same length.

Returns the status of the interior-point solution: InteriorParam or nothing to use the default settings. Also most of the parameters of the glpsol standalone solver can be controlled via the GUI.

GMPL is extremely easy to learn Consider the example glpk documentation — nothing more to say. Prob object used by the Glpk documentation solver.

Glpk documentation input, v represents the glpk documentation b ; at output, it contains the vector x. The linear programming problem can be formulated as follows: Whenever an invalid condition is detected e. The relaxed requirements for inputs are also valid for arrays e.


Robbie Morrison October 18, at 7: Retrieves control parameters, which are used on computing and updating the basis factorization associated with the problem object, and stores them in the GLPK. Retuns the memory block allocated for the subproblem whose reference number glpk documentation p.

There are 5 such functions:. Returns the index of the basic variable k which is associated with the specified column, or 0 if glpk documentation variable is glpk documentation. Possibility to use GLPK through a simple matlab command, namely glpk.

Returns 0 if no row with the given name is found. It returns coef1, var1, value1, coef2, var2, value2 rather then taking them as glpk documentation in the argument list. Sets the kind for the specified column for mixed-integer programming. Checks if the problem object encodes a CNF-SAT problem instance, in which case it returns 0, otherwise returns non-zero. The GLPK package includes the following main components: The main discussion list is help-glpk gnu.

The routine interior is a driver to the LP solver based on the primal-dual interior-point method. You are commenting using your WordPress. Makes the cut pool empty deleting all existing rows cutting plane constraints from it. Assigns a name to the objective function or deletes it if name is empty or nothing.
