Fig. 12.

Example run of the GA visualised in the space of weighting parameters for (a) the cost function, (b) nodal difference and (c) force difference functions. Red crosses and circles represent all the individuals that happened to be instantiated during the 100 generations. The black line shows the evolution of the best fitted individuals from each generation, converging on the one defined by the pair [0.0688, 0.0874]. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
