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 learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

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 learning method algorithm") OR ("modified static optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified learning method algorithm ) or ( modified static optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") or ("modified static optimization algorithms"))*.
