Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
convolution algorithms » evolution algorithm, solution algorithm
near optimization » network optimization, stage optimization, _ optimization
active learning » machine learning
modified near » modified seird, modified adam

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

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