Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"modified orca predation algorithm" » "modified orca predators algorithm", "modified orca estimation algorithm", "modified dorca predation algorithm", "modified orcad predation algorithm", "modified ohca predation algorithm"

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

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