QapSolver

QapSolver is a powerful and fast QAP solver that uses a state-of-the-art metaheuristic algorithm. It can handle any QAP instance, from small to very large, and find near-optimal solutions in minutes or seconds.

QapSolver supports two input data formats: QAPLIB format (see https://coral.ise.lehigh.edu/data-sets/qaplib/) or Excel workbook (.xlsx) with matrices A (distances) and B (flows) in the first two sheets. The matrix coefficients can be floating point numbers, but not negative.

QapSolver is very easy to use. Just follow these simple steps:

o Load matrices in QAPLIB format or as Excel workbook.

o Click the Start button.

o Wait for the solver to run. The time depends on the size of the instance and your hardware. QapSolver uses parallel solver, so more cores means faster computation.

o Save the solution in one of the text formats or as Excel workbook.

o You can restart the solver several times and choose the best solution.

o You can also change the heuristic settings if you want to experiment with different parameters.

QapSolver is fully functional during the trial period. Try it now and see how it can solve your QAP problems quickly and efficiently.
