Are there any Mixed Integer Linear Programming(MILP) solver for Python? Can GLPK python solve MILP problem? I read that it can solve Mixed integer problem. I am very new to linear programming prob...

Given a linear system Ax = b, where matrix A and vector b have integer values, I want to find all nonnegative integer vectors x that solve this equation. So far, I have found some techniques such ...

I'm using the PuLP module in Python to formulate a mixed integer program. I am trying to work out how to set a MIP start (i.e. a feasible solution for the program to start from) via the PuLP interf...

I'm trying to figure out how to get the complete list of possible solutions from the ortools.sat.python.cp_model. I understand I can print them, as in the example below, but it is not clear to me h...

I am trying to create an optimal shift schedule where employees are assigned to shift times. The output should aim to spend the least amount of money. The tricky part is I need to account for speci...

I'm using cvxpy within python to solve a particular type of assignment problem. I'd like to assign M people to N groups in a way that minimizes cost, with the following constraints on groups: Gro...

Trying to add the following constraint in Gurobi/Python: Code N_SERVERS = 5 #number of servers C_SERVER = [1]*N_SERVERS N_NODES = 3 #number of nodes C_NODES = [2]*N_NODES #create model m...

I have a set of metallic sliding pieces which are constrained to the x and y axis in following way: I would need to maximize the horizontal distance among all pieces constrained by the same slid...

I need to solve a system of linear diophantine equations with either numpy or sympy. Is there any way to constrain numpy's linalg.solve/linalg.lstsq method to return only integer solutions? (proba...

I noticed that R doesn't use all of my CPU, and I want to increase that tremendously (upwards to 100%). I don't want it to just parallelize a few functions; I want R to use more of my CPU resources...

Consider m by n matrices M, all of whose entries are 0 or 1. For a given M, the question is whether there exists a non zero vector v, all of whose entries are -1, 0 or 1 for which Mv = 0. For examp...

This problem appeared in a challenge, but since it is now closed it should be OK to ask about it. The problem (not this question itself, this is just background information) can be visually descri...

I have an optimization problem that has in the objective function 2 multiplied variables, making the model quadratic. I am currently using zimpl, to parse the model, and glpk to solve it. As they ...

I am running PuLP Programming Library in Python 2.7.8, Windows 32 bit. I'm using GLPK as my solver for a mixed integer linear programming problem. The solver converges to approx. 1% of the optimal ...

I'm trying to solve integer programming problems. I've tried both use SCIP and LPSolve For example, given the final values of A and B, I want to solve for valA in the following C# code: Int32 a =...

I'm fairly new to R and I'm trying to write a script for what I used to do with Solver in Excel. In my data below, I have a list of workers with job types A-E. Each worker has a salary and a produc...
