Module contents¶

This module contains a Solver baseclass and several implemented subclasses.

Solvers are used to with pywr.core.Model classes to solve the network allocation problem every time step.

Currently there are only linear programme based solvers using,

GLPK
LPSolve55

class pywr.solvers.CythonGLPKSolver(*args, **kwargs)¶

Bases: pywr.solvers.Solver

Python wrapper of Cython GLPK solver.

This is required to subclass Solver and get the metaclass magic.
