Solver Utilities

Check which Pyomo solvers and OR-Tools backends are installed and available in the current environment (e.g. before choosing a solver for OPF or TEP).

Functions are found in pyflow_acdc.solver_utils.

check_available_solvers(pyomo_solvers=None, include_ortools=True, verbose=True)[source]

Report which Pyomo solvers and OR-Tools backends are installed and available.

Parameters:

  • pyomo_solvers (list of str, optional) – Solver names to probe; defaults to a built-in list (cbc, glpk, ipopt, bonmin, gurobi, …).

  • include_ortools (bool, optional) – When True, also report OR-Tools LP/MIP backend availability.

  • verbose (bool, optional) – Print a human-readable report to stdout.

Returns:

Keys include pyomo_available, pyomo_errors, and (when include_ortools) ortools_installed, ortools_available.

Return type:

dict

is_pyomo_solver_available(solver_name)[source]

Return True if a Pyomo solver is installed and available.

Uses SolverFactory(...).available(False) so missing executables are detected without raising (unlike available() with no argument).

Return True if a named Pyomo solver executable is installed (e.g. probe for 'gurobi' before choosing array MIP/CSS defaults — see Wind Farm Array Sizing Module).
