                This year GECCO took place in Madrid on 11-15 of July. Many interesting tutorials and workshops were presented in this conference. On 14th of July we presented our paper about a new repair method for constrained optimization. You can download the presentation slides from here.  

A New Repair Method For Constrained Optimization

Veröffentlicht: von

Many real-world optimization problems are dealing with constraints. The valid solution for constrained optimization problems (COP) lies somewhere in the feasible region which is a sub-set of the input-space. The borders of the feasible area are defined by one or many constraints. Existance of constraints makes the optimization problems more demanding. There are different approaches to... Mehr »
