Fig. 7From: Global optimization of a numerical two-layer model using observed data: a case study of the 2018 Sunda Strait tsunamiGlobal optimization results, where the colored points give the value of the objective function for each simulation run. The number of simulations was set to 1500 with 30 populations over 50 iterations, and the red dashed box in the figure represents the approximated area of the last iterationBack to article page
