Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm"
"modified stochastic optimized algorithm" » "modified stochastic optimization algorithm", "modified stochastic optimized algorithms", "modified stochastic optimizer algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified stochastic optimized algorithm") or ("modified quadratic optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimized algorithm") OR ("modified quadratic optimization algorithm")).
• Removing quotes may allow a broader search: (( modified stochastic optimized algorithm ) or ( modified quadratic optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimized algorithm") or ("modified quadratic optimization algorithm"))*.
