Galperin and Wigderson proposed a succinct representation for graphs, that uses number of bits that is logarithmic in the number of nodes. They proved complexity results for various decision problems on graph properties, when the graph is given in a succinct representation. Later, Papadimitriou and Yannakakis showed, that under the same succinct encoding method, certain class of decision problems on graph properties becomes exponentially hard. We consider the complexity of the Permanent problem when the graph/matrix is given in a restrict succinct representation. We present an optical architecture that is based on the holographic concept for solving balanced inputs of the Succinct Permanent problem.

The talk will include both a theoretical results (relating establishing a computational complexity of some problems) and an optical implementation of the proposed algorithm.
