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