Perhaps you should try some spelling variations:
"modified static optimization algorithmss" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithms", "modified static optimization algorithmsss", "modified static optimisation algorithmss", "modified static estimation algorithmss", "modified stage optimization algorithmss", "modified stochastic optimization algorithmss", "modified staffing optimization algorithmss"
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization 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: (("modified allocation optimization algorithm") or ("modified static optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimization algorithm") OR ("modified static optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) or ( modified static optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") or ("modified static optimization algorithmss"))*.
