construct/mc pysms chromatic girth
construct/mc pysms chromatic girth: a task in MathConstructOptimize-Envs-harbor (Harbor dataset). Construct a simple undirected graph on the 22 vertices 0..21 such that: - the graph has at least 17 edges - the chromatic number is at most 4: the vertices can be coloured with colours 0..3 so that…
The task
Construct a simple undirected graph on the 22 vertices 0..21 such that: - the graph has at least 17 edges - the chromatic number is at most 4: the vertices can be coloured with colours 0..3 so that adjacent vertices get different colours (you must also give such a colouring) - the girth is at least 7: the graph has…
