We study path integration on a quantum computer that performs quantum summation. We assume that the measure of path integration is Gaussian, with the eigenvalues of its covariance operator of order j^{-k} with k1. For the Wiener measure occurring in many applications we have k=2. We want to...

A dynamical-systems-based model of computation is studied. We demonstrate the computational ability of nonlinear mappings. There exists a switching map system with two types of baker's map to emulate any Turing machine. Taking non-hyperbolic mappings with second-order nonlinearity (e.g., the...

This paper deals with transportation problems whose demand vectors can be permuted. This additional freedom makes these problems ??-hard, even in the case that the cost matrix fulfills a Monge property. We outline some solution procedures based on good lower and upper bounds. Copyright...
