A novel version of Ant Colony Optimization (ACO) algorithms for solving continuous space problems is presented in this paper. The basic structure and concepts of the originally reported ACO are preserved and adaptation of the algorithm to the case of continuous space is implemented within the general framework. The stigmergic communication is simulated through considering certain direction vect...

The 8D method is a complex tool for solving problems of significant scale which are hard for individuals to solve and involve solutions which require extra resources. However, several problems have been detected in the method of 8D’s usage in modern organizations. The main aim of this paper is to define critical factors which lead to the demotivation of problem-solving teams. The primary aim of...

BACKGROUND: One of limitation factor in agricultural plants production in dry areas, supply requires water. Also nutrition crop management is a necessary strategy for achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assessment the effects of different irrigation regimes and several amount of nitrogen fertilizer on seed nutrition...

The demand to obtain answers to highly complex problems within strong-field gravity has been met with significant progress in the numerical solution of Einstein's equations - along with some spectacular results - in various setups. We review techniques for solving Einstein's equations in generic spacetimes, focusing on fully nonlinear evolutions but also on how to benchmark those results with p...

A general approach to optimally solve multiple facility location problems based on the “Big Triangle Small Triangle” approach to solving single facility problems is proposed. The proposed procedure is especially effective when the solution is constrained to a given polygon such as the convex hull of demand points. The procedure is tested on the two facilities Weber problem with attraction and r...
