Perhaps you should try some spelling variations:
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified made » modified male, modified adam, modified df
made solution » model solutions, water solution, nacl solution

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified made solution algorithm ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified made solution algorithm ) or ( modified objective optimization algorithm ))*.
