The building-block hypothesis states that the GA works well when short, low-order, highly-fit schemas recombine to form even more highly fit higher-order schemas. The ability to produce fitter and fitter partial solutions by combining building blocks is believed to be a primary source of the GA’s search power, but the GA research community currently lacks precise and quantitative descriptions o...

the strategic pricing decisions of assembly products in assembly products supply chain are studied in this paper. firstly, a two-stage assembly products supply chain model is developed. by building nash game model, the nash equilibrium solution of pricing strategy of supplier and assemblers is obtained. next, a union decision model is built to analyze the optimal combination pricing strategy of...

In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method under minimal regularity hypothesis. Test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.
