Our objective in this paper is to compare the performance of the Differential Evolution (DE) and the Repulsive Particle Swarm (RPS) methods of global optimization. To this end, some relatively difficult test functions have been chosen. These functions are: Perm, Power-Sum, Bukin, Zero-Sum,...

In this paper we compare the performance of the Differential Evolution (DE) and the Repulsive Particle Swarm (RPS) methods of global optimization. To this end, seventy test functions have been chosen. Among these test functions, some are new while others are well known in the literature; some are...

Technologies that are used in different production processes of miscellaneous industries are known as cross-sectional technologies. The economic importance of these technologies normally is measured by economic benchmarks of the producing industry. However, the impact of these tech-nologies for...

In this paper we test a particular variant of the (Repulsive) Particle Swarm method on some rather difficult global optimization problems. A number of these problems are collected from the extant literature and a few of them are newly introduced. First, we introduce the Particle Swarm method of...

The work constructs projections till 2030 for health care expenditures of Italian Regional Health Care Systems. Three different schemes of financing are hypothesised, with three different levels of solidarity between Regions. Financing is always supposed to cover the entire exigency of...
