optaplanner - Hard score calculation in vehicle routing -


currently using optaplanner calculating score in cvrp problem.

if (demand > capacity)      hardscore -= (demand - capacity);

if there heterogeneous fleet, how can calculate hard score?

i want use vehicle small capacity if number of demand less vehicle assigned optaplanner.

don't mix 2 constraints. these 2 different constraints:

  • each vehicle must have enough capacity (usually hard constraint) - implemented in optaplanner example.
  • prefer using smaller vehicles on bigger ones (usually soft constraint). there's price per km per vehicle type, factors in distance driven in soft score penalty.

just implement second constraint, starting optaplanner vrp example.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
