Graphisomorphismus
WebThis problem is similar to the sub-graph isomorphism problem [424–426], and it is known that the directed sub-graph isomorphism problem is NP-complete [117]. Template generation consists of creating new templates (e.g. [356,359,360,363,370,371,374,391,393,394–402,404–410,412,425–428]).
