I ran the unit test on the old ProbLog model to ensure the unit test is solving the problem, and this is confirmed by the old ProbLog model failing the unit test, with a high confidence rule being triggered: |

Addressing issue identified in #1027, where skips were being evaluated as false. This PR introduces wrappers
passed()andfailed()into the ProbLog model that usetry_call()statements. Skipped heuristics are no longer defined in the ProbLog model, which is why thistry_call()statement is used. This means that evaluatingfailed(heuristic)will be false if the heuristic passed, or if it was not defined (i.e. was skipped). Similarly, for evaluatingpassed(), this will be false if the heuristic failed, or if it was not defined. This should handle situations where skips should not cause rules they are part of to trigger. This method was the easiest way to keep as much of the ProbLog model in a static string as possible, without having to perform extensive string operations.Rule IDs have also been added for debugging purposes, and a method to extract them, so that it is evident what rule was triggered.
