Name:Grill

Description:structurial engineering, global optimization, genetic algorithms.

Abstract:The optimal design of grillage-type foundations is a specific class of optimization problems in civil engineering. The grillages which consist of piles and connecting beams, are the most popular and effective scheme of foundations, especially in case of weak grounds. The optimal grillage is the one that meets twofold criteria: it is supported with minimal quantity of piles, and its connecting beams receive minimum possible torques. The problem is solved by the global optimization methods: random search and its modifications, simulated annealing and genetic algorithms. Performed numerical experiments are fully independent of each other. No communication between processes is necessary. Thus, such optimization problems are ideally suited for grid computing. Technical information: Grill software is academic, open source, developed at Vilnius Gediminas Technical University. Depending on problem size it requires a lot of CPU power. Estimated number of CPU hours for our current problem solving is 50 0000.
