The promise of medical innovation has long evoked social commentary, particularly when personal reproductiveautonomy may be impacted. Development of the oral contraceptive, effective and safe surgical sterilization, and later IVF and ICSI are among the revolutionary developments where initial reaction was dubious, but eventually, each was accorded mainstream status as clinical experience accumu...

expert systems can help to build banks customers' credit scoring models. here, selection of key features of the credit scoring is important. also, it is possible to express the features values as fuzzy. the problem is how to improve features selection by genetic algorithm, in way that these features can be employed as input in fuzzy expert system. this paper presents a hybrid credit scorin...

In this paper we construct robust models for active portfolio management in a market with transaction costs. The goal of these robust models is to control the impact of estimation errors in the values of the market parameters on the performance of the portfolio strategy. Our models can handle a large class of piecewise convex transaction cost functions and allow one to impose additional side co...

The latest generation of SAT solvers (e.g. [9, 5]) generally have three key features: randomization of variable selection, backtracking search, and some form of clause learning. We present a simple algorithm with these three features and prove that for instances with constant ∆ (where ∆ is the clause-to-variable ratio) the algorithm indeed has good worst-case performance, not only for computing...

Participants in e-commerce and other forms of online collaborations tend to be selfish and rational, and therefore game theory has been recognized as particularly relevant to this area. In many common games, the joint strategy of the players is described by a list of pairs of actions, and one of those pairs is chosen according to a specified correlated probability distribution. In traditional g...
