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