Moderately Exponential Approximation: Bridging the Gap Between Exact Computation and Polynomial App problems. We show how one can match ideas from both areas in order to design approximation algorithms achieving ratios unachievable in polynomial time (unless a very unlikely complexity conjecture is confirmed) with worst-case complexity much lower (though super-polynomial) than that of an exact co

Effect Oriented Planning of Joint Attacks,iven number of resources which can be, for example, fighter aircraft, unmanned aerial vehicles, or missiles. The targets could be radar stations or other surveillance equipment, with or without defensive capabilities, which the attacker wishes to destroy. Further, some of the targets are defended, b

Competitive Multilevel Capacity Allocation,ularly examine the effects of customers’ competition for the offered service level on the facility location decisions. We consider two types of decision makers, the producer who tries to provide at facilities the best level of service at minimum cost and the customers who make their choices in order

Open-Pit Mining with Uncertainty: A Conditional Value-at-Risk Approach, the maximum value. It is a hard task to know with certainty the quantity and quality of ore in the ground. This geological uncertainty and also the future market behavior of metal prices and foreign exchange rates, which are always uncertain, make mining a high risk business. Value-at-Risk (VaR) is

A Parallel Implementation of the Revised Simplex Algorithm Using OpenMP: Some Preliminary Results,olving Linear Programming problems (LPs). The aim of this paper is to present a parallel implementation of the revised simplex algorithm. Our parallel implementation focuses on the reduction of the time taken to perform the basis inverse, due to the fact that the total computational effort of an ite

Determining the Minimum Number of Warehouses and their Space-Size for Storing Compatible Items,red floor space housing of every item is known. The method developed here refers to store compatible items in the same warehouse in order to diminish the maximum necessary space-size of every warehouse and consequently to the determination of the minimum number of needed warehouses. The problem is f
