Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithm » optimized algorithms, optimizer algorithms
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: (( modified near optimized algorithm ) or ( modified parameters optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified near optimized algorithm ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified near optimized algorithm ) or ( modified parameters optimization algorithms ))*.
