This paper studies a pricing game in which two sellers compete to sell a product to a customer with bounded rationality. The sellers have different production costs in determining their respective prices to offer to the buyer. The buyer prefers the seller offering a lower price, but may suffer...

Cardinality constrained mean-variance (CCMV) portfolio selection problem is commonly formulated as a mixed integer quadratic program (MIQP) that can be solved by a branch-and-bound scheme or metaheuristics. Yet, computational efficiency remains to be a major issue. In this study, we propose a...

An alternative smoothing method for the high dimensional max functionhas been studied. The proposed method is a recursive extension of thetwo dimensional smoothing functions. In order to analyze the proposedmethod, a theoretical framework related to smoothing methods has beendiscussed. Moreover,...
