in this research, performance of pattern search algorithm (ps) was investigated in order to optimize the nonlinear muskingum model parameters in contrast with the general algorithms, for wilson and karoun floods routing. wilson flood routing has been chosen to compare the ability of ps algorithm with other algorithms and, karoun flood routing has been chosen for a better evaluation of ps. the r...

Numerical experiments on most gauge theories coupled with matter failed to observe string-breaking effects while measuring Wilson loops only. We show that, under rather mild assumptions, the overlap of the Wilson loop operator with the broken-string state obeys a natural upper bound implying that the signal of string-breaking is in general too weak to be detected by the conventional updating al...

A new approach to Markov chain Monte Carlo simulation was recently proposed by Propp and Wilson. This approach, unlike traditional ones, yields samples which have exactly the desired distribution. The Proppp Wilson algorithm requires this distribution to have a certain structure called monotonicity. In this paper, it is shown how the algorithm can be extended to the case where monotonicity is r...

This paper discusses a problem in which  decentralized supply chains enter the market simultaneously with no existing rival chains, shape the supply chains’ networks, and set wholesale and retail prices in a noncooperative manner. All the chains produce either identical or highly substitutable products. Customer demand is elastic and price-dependent. A three-step algorithm is proposed to solve ...

We have already presented at a Lattice conference [1] an algebraic algorithm that allows to apply the coordinate-space method by Lüscher and Weisz [2] to two-loop lattice integrals with gluon and Wilson-fermion propagators. In order to test the method, we have recently redone [3] a twoloop computation of the critical mass for Wilson fermions [4]. For Wilson fermions, the dressed inverse fermion...
