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 allocation estimation algorithmss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithms", "modified allocation optimization algorithmss", "modified motion estimation algorithmss"

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

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