Perhaps you should try some spelling variations:
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"
"modified changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimized algorithms"

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

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