Perhaps you should try some spelling variations:
regulation algorithm » evolution algorithm, predation algorithm, estimation algorithm
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
objective optimizer » objective optimal, objective optimization
modified legal » modified near, modified thermal

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 legal regulation algorithm ) OR ( modified objective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified legal regulation algorithm ) or ( modified objective optimizer algorithms ))*.
