摘要: Which plane graphs admit a straight line representation such that all faces have the shape of triangle? In previous work we studied necessary and sufficient conditions based on flat angle assignments, i.e., selections angles graph size π in representation. A assignment fullfills these is called good. The complexity for checking whether has good remains unknown.
