source: /scipy/optimize/_linprog_util.py :919

Signature

def _parse_linprog ( lp , options , meth )

Summary

Parse the provided linear programming problem

Extended Summary

_parse_linprog employs two main steps _check_sparse_inputs and _clean_inputs. _check_sparse_inputs checks for sparsity in the provided constraints (A_ub and ``A_eq) and if these match the provided sparsity optional values.

_clean inputs checks of the provided inputs. If no violations are identified the objective vector, upper bound constraints, equality constraints, and simple bounds are returned in the expected format.

Parameters

lp : A `scipy.optimize._linprog_util._LPProblem` consisting of the following fields:

c: c
A_ub: A_ub
b_ub: b_ub
A_eq: A_eq
b_eq: b_eq
bounds: bounds
x0: x0

options : dict

A dictionary of solver options. All methods accept the following generic options:

maxiter
maxiter
disp
disp

For method-specific options, see show_options('linprog').

Returns

lp : A `scipy.optimize._linprog_util._LPProblem` consisting of the following fields:

c: c
A_ub: A_ub
b_ub: b_ub
A_eq: A_eq
b_eq: b_eq
bounds: bounds
x0: x0

options : dict, optional

A dictionary of solver options. All methods accept the following generic options:

maxiter
maxiter
disp
disp

For method-specific options, see show_options('linprog').
