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 20 vertices 0..19 such that: - the graph has at least 21 edges - the chromatic number is at most 3: the vertices can be coloured with colours 0..2 so that…
The task
Construct a simple undirected graph on the 20 vertices 0..19 such that: - the graph has at least 21 edges - the chromatic number is at most 3: the vertices can be coloured with colours 0..2 so that adjacent vertices get different colours (you must also give such a colouring) - the girth is at least 7: the graph has…
