Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
quadratic optimizer » quadratic optimization
modified adaptive » 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 quadratic optimizer algorithms ) OR ( modified adaptive optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified quadratic optimizer algorithms ) OR ( modified adaptive optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified quadratic optimizer algorithms ) OR ( modified adaptive optimisation algorithm ))*.
