Perhaps you should try some spelling variations:
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
predation algorithm » predators algorithm, estimation algorithm
objective optimizer » objective optimal, objective optimization
legal predation » legal regulation, legal persuasion, legal protection
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 predation algorithm ) OR ( modified objective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified legal predation algorithm ) or ( modified objective optimizer algorithms ))*.
