The ShortestPathLength method returns the optimal path length given the Distance definition. In most SBC cases you won’t have the information necessary to implement a method that returns the optimal solution. The NumberOfPossiblePaths method just computes n! where n is the number of cities. In...

A decision problem has a single boolean output: Yes or No. Let’s understand more about when a decision problem becomes non-deterministic. Understanding NP Problems Generally, those sets of decision problems that can be solved under a polynomial-time are categorized as ‘P’. The decision proble...
Since the VRP solver tries to minimize cost, it will try to limit the arrive/depart delays and thus choose the single-route option. (Note that multiple routes may need to be sent when other constraints—such as specialties, time windows, or capacities—require it.) The unit for this...
(A technical point is that the particular neural net we’ve used here has the property that all paths between any given pair of nodes always have the same length—so if any path is found, it can be considered “the shortest”. A rule like {A AAB, BBA B} doesn’t have this property...
Intelligence, in sum, has come to be regarded as not a single ability, but an effective drawing together of many abilities. This has not always been obvious to investigators of the subject, however, and, indeed, much of the history of the field revolves around arguments, regarding the ...
