A python Linear Programming API
Details for the issue -------------------- #### What did you do? I attempted to use the timeLimit parameter with the pulp.FSCIP_CMD solver to restrict the optimization time for solving a linear...
Hi, I'm using `PuLP==2.7.0` (tried also to install pulp from source). I got `Infeasible` status on this solvable problem : ``` lp_problem = LpProblem('my_problem', LpMinimize) x_0 = LpVariable('x_0', lowBound=0, upBound=1,...
This is a followup to https://github.com/coin-or/pulp/issues/699. I'm attaching the issue text below: Hello, I’m working on a real-time decision making tool that uses PuLP with the CBC solver to solve...
This patch solves two issues in HiGHS API (actualSolve method): 1) Code for parsing a list of additional options had a typo in method name (should be startswith) 2) The...
Details for the issue -------------------- #### What did you do? I currently need to read a `.mps` file back into Pycharm using `LpProblem.fromMPS([file directory], sense=Lp.Maximize)`. However, when doing things on...
LpVariable dicts issue parsing indices of the form [(a1, b1, c1), (a2, b2, c2), ..., (an, bn, cn)]
Details for the issue -------------------- When creating a collection of LpVariables using the class method dicts, using an index that is a list of tuples in order to emulate a...
For SCIP only, it report Not Solved/No Solution Exists when the solver found a feasible solution already. CBC and Cplex works fine. i can see from scip output that a...
I would like to revisit this topic again (https://github.com/coin-or/pulp/issues/155). Is there **any** ways for us to **re-write** the hashcodes created by multiple child processes by **exporting** the model (in `.mps`...
Hi Experts, i use below scripts to load problem from JSON. ` import pulp as lp d, loaded_problem = lp.LpProblem.fromJson('saved_problem.json') loaded_problem.solve() ` it shows `At line 1594 ENDATA Problem MODEL...
Details for the issue -------------------- #### What did you do?
