library10.8.4pypypiunverified

passagemath-glpk provides a linear and mixed integer linear optimization backend using GLPK (GNU Linear Programming Kit) for the passagemath library. It enables the construction and solution of linear programming (LP) and mixed-integer linear programming (MILP) problems. Version 10.8.4 supports Python >=3.11,<3.15. The package is part of the passagemath ecosystem, which reimplements functionality previously provided by SageMath.

Quickstart example: solve a simple MILP using GLPK backend.

from passagemath.numerical.mip import MixedIntegerLinearProgram # Create MILP instance with GLPK backend p = MixedIntegerLinearProgram(solver='GLPK') # Define variables x = p['x'] y = p['y'] # Add constraints p.add_constraint(x + 2*y <= 4) p.add_constraint(2*x + y <= 6) # Set objective p.set_objective(3*x + 4*y) # Solve p.solve() # Get solution print(f"x = {p.get_values(x)}") print(f"y = {p.get_values(y)}")

Debug

Known issues

breakingGLPKBackend import path changed from sage.numerical.backends.glpk_backend to passagemath.glpk.backend.

fix

Change import to 'from passagemath.glpk.backend import GLPKBackend'.

affects: Migrating from SageMath (any version) to passagemath-glpk >=10.8

breakingMixedIntegerLinearProgram now requires 'solver' parameter; default may not be GLPK. In SageMath, default was GLPK.

fix

Explicitly pass solver='GLPK' when creating MixedIntegerLinearProgram.

affects: passagemath-glpk >=10.0

gotchaGLPK backend may not be thread-safe; avoid concurrent solve calls.

fix

Serialize solve calls or use multiprocessing with separate processes.

affects: All versions
