New Reducible Configurations for Graph Multicoloring with Application to the Experimental Resolution of McDiarmid-Reed's Conjecture

A $(a,b)$-coloring of a graph $G$ associates to each vertex a $b$-subset of a set of $a$ colors in such a way that the color-sets of adjacent vertices are disjoint. We define general handle reduction methods for $(a,b)$-coloring of graphs for $2\le a/b\le 3$. In particular, using necessary and suffi...
