The genetic algorithm is numbered among less formal methods which allows using it in different areas including forecasting. However, there is a question about efficiency of that instrument. We decided to check inner procedures of the algorithm affecting gaining speed and quality of solutions. We...

One of the most known combinatorial problem is a Travelling Salesman Problem. In this paper a extended version is considered – multisalesman problem, which is known in the literature as a vehicle routing problem. It is very easy to define this NP-hard problem, but to find a optimal solution is...
