Intuitively, a problem isin P1 if thereisan efficient (practical) algorithm tofind a solutiontoit.On the other hand, a problem is in NP 2, if it is first efficient to guess a solution and then We study a variety of natural constructions from topological combinatorics, including matching complexes as well as other graph complexes, from the perspective of the graph minor category of [MPR20]. Combinatorics - Combinatorics - Graph theory: A graph G consists of a non-empty set of elements V(G) and a subset E(G) of the set of unordered pairs of distinct elements of V(G).

It consists of several heaps of counters and the opponents alternately remove counters from the heaps. Note that, in graph theory, the term trail has a different meaning, i.e, a type of walk on a graph in which all edges are distinct (as defined by Harris, Hirst, and Mossinghoff, 2008).
