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 learning evolution algorithm" » "modified learning solution algorithm", "modified learning evolutionary algorithm", "modified learning convolution algorithms", "modified learning convolution algorithm", "modified learning emotion algorithm", "mobile learning evolution algorithm", "modified caging evolution algorithm"

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