In this paper the problem of parametric identification of a historic masonry tower model is discussed. The tower leans and its foundation stiffness is a concern to authorities. The authors identified some modal characteristics of the tower, natural frequencies and mode shapes. It is known, based on the first mode shape identified, that the structure behaves like a stiff solid on elastic foundation...
In the paper we present fast implementation of multi-population (1+1)-ES. Evolutionary Strategies are vastly time consuming when used to solve problems with large domain and huge number of variables. We propose the idea of accelerate ES computation using GPU. Due to SIMD architecture GPU ES implementation is more effective when the size of an optimized problem is raising.
