linear programming kit – documentation files. GLPK (GNU Linear Programming Kit) is intended for solving large-scale linear programming (LP), mixed integer. The GLPK library comes with many bells and whistles, including dual simplex, Mixed Integer Programming (MIP), and other related problems. Here’s a list, taken.

Makhorin, allowing you to solve linear optimization problems. Right now, this library does not support any of flpk bells and whistles; it just allows basic primal simplex solving.

I believe I have designed and implemented the lp-solve function in such a way that this should not dooc possible. The linear programming problem can be formulated as follows: Okay, so what kind of constraints are possible?

Well, each constraint consists of a single equality, of the form.

ddoc These auxiliary variables must occur only once each, on the left-hand side of the corresponding constraint. The objective function is a linear combination of structural variables.


It may be either maximized or minimized, as you dic. Along with these constraints, each variable, both structural and auxiliary, comes with a pair of possibly infinite bounds.

So, for instance, you can specify that auxiliary variable b ranges between and The objective function includes a constant term and a linear combination of structural variables:. The constraints each include the name of an auxiliary variable and a linear combination of structural variables:. Voc, the set of bounds provides bounds for both the auxiliary and structural variables.

Each bound contains the name of a variable, and a low and high boundary. The low boundary can be ‘ neginfindicating no lower bound, and the high boundary can be ‘ posinfindicating no upper bound.

The lower and upper bound can be equal, indicating that the g,pk variable is fixed. The result is a list containing the maximal or minimal value of the objective function, along with a list of lists mapping structural variables to the values that produce that optimal value, unless no solution is possible.


There are two ways that this can be signalled; either as a list containing the symbol ‘ bad-result and then a FailCode definition belowor as a list containing the symbol ‘ bad-status and then a SolutionStatus also defined below.

You have three kinds of guests: Children, Adults, and Chickens. Each adult wants one slice of bread, a patty, and two pickles.

GLPK/GMPL (MathProg)

Each child wants two slices of bread, and a patty. Gopk can add arbitrary further constraints on this: To model this, we divide adults into adults chaperoning kinds ak and adults chaperoning chickens ac.

If I understand the internals of Racket correctly, making use of this would require separately compiling a C stub that establishes a jump buffer and uses setjmp before calling into each GLPK library function. The Gnu Linear Programming Kit.
