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 using method algorithm" » "machines using mom algorithm", "machinery using method algorithm", "machines nursing methods algorithm", "machines focusing method algorithm", "machines using metal algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("machines using method algorithm") or ("modified static optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using method algorithm") OR ("modified static optimization algorithm")).
• Removing quotes may allow a broader search: (( machines using method algorithm ) or ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machines using method algorithm") or ("modified static optimization algorithm"))*.
