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 df solution algorithm" » "modified df evolution algorithm", "modified df convolution algorithms", "modified df evolutionary algorithm", "modified _ solution algorithm", "modified adam solution algorithm", "modified bi1 solution algorithm", "modified drug solution algorithm", "modified up solutions 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 df solution algorithm") or ("modified static optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df solution algorithm") OR ("modified static optimization algorithm")).
• Removing quotes may allow a broader search: (( modified df solution algorithm ) or ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df solution algorithm") or ("modified static optimization algorithm"))*.
