Perhaps you should try some spelling variations:
multiobjective predation » multiobjective optimization, multiobjective design
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
predation algorithm » predators algorithm, estimation algorithm

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified multiobjective predation algorithm ) or ( modified objective optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified multiobjective predation algorithm ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective predation algorithm ) or ( modified objective optimization algorithms ))*.
