Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
pulse optimization » policy optimization, game optimization, qoe optimization
modified pulse » modified male, modified passive

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

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