| Abstract: | We base the ALGACEA-1 method on Clarke–Wright's savings estimates, using Monte Carlo techniques for node selection. This procedure controls the assigned probabilities for node selection using a bounded Entropy function. Similarly, we have discussed the parameter tuning for this method with the purpose of obtaining a good algorithm performance. Finally, some computational results are given to show the quality of the solutions provided by ALGACEA-1 in a real case and in some benchmarking instances. |
