Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
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 objective optimisation algorithm ) OR ( modified made solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) or ( modified made solution algorithm ))*.
