A problem with the solution printing and objective value, please help!
回答済みHello, for my bachelors thesis that is due in a week, i am working on an MILP for a heterogenous CVRP and I am running into a slight problem and am not quite sure what I should do to fix it. The MI...

My model is infeasible, i have found the constraint which is causing it but i can\t find out what the reason is.
回答済みHi, Currently, I am working on a heterogeneous CVRP MILP. The code i have runs for the homogeneous cases however, in the case of heterogenous vehicles, it does not. The model becomes in feasible...

My model does not find a single solution, even if the time limit is set to high numbers.
回答済みHello, i am currently trying to solve a MILP for a HCVRP in python. My MILP model is not infeasible but does not provide a solution, even if there are only 25 nodes. I am trying to find out whats w...

My model is infeasible. Can someone please help me?
回答済みHi, i currently have the following code for an MILP program modelling a CVRP situations with multiple vehicles. My model does not run because it is infeasible, however I am not quite sure why it sh...

Hi Riley, I have, and it is not necessarily that it does not try to optimize the objective function. It does not find a solution, as the solution count is 0. I cannot find what is wrong. The variab...

My model does not work right, can someone help me?
回答済みHello, currently i am trying to automize validating my solution of a Capacitated Vehicle Routing Problem of an Ant colony optimization algorithm. The code runs and gives me a solution, however, whe...

回答済みHello, my code should model the real-life situation of visiting moisture level sensors. Some of these sensors are at the same location as the depot and therefore my distance matrix seems a bit weir...
