Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
convolution algorithm » convolution algorithms, evolution algorithm, solution algorithm
based optimization » game optimization, market optimization, qoe optimization
modified based » modified male

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

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