The final chapters apply everything to real engineering problems:
To maintain diversity on the Pareto front (so you don't get 100 similar designs and miss the extreme lightweight option), Deb introduced crowding distance. This selects designs from sparser regions of the trade-off surface. optimization for engineering design kalyanmoy deb pdf work
This is why engineers seek out the PDF. Deb introduces Genetic Algorithms (GAs) tailored for engineering. The final chapters apply everything to real engineering
