Open problems in combinatorial group theory
WebA public-key cryptosystem inspired in part by the Wagner-Magyarik idea, but the idea is vague, and it is dicult to find a secure realization of this idea. We analyze and critique the public-key cryptosystem, based on combinatorial group theory, that was proposed by Wagner and Magyarik in 1984. This idea is actually not based on the word problem but … WebGiven a (combinatorial) problem Π, a stochastic local search algorithm for solving an arbitrary problem instance π ∈ Π is defined by the following components:. the search …
