In this paper we introduce a simple ant based algorithm for solving a copper mine planning problem. In the last 10 years this realworld problem has been tackled using linear intege...
Abstract. Ubiquitous computing is a challenge for the design of middleware. The reasons are resource constraints, mobility, heterogeneity, etc., just to name a few. We argue that s...
