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 objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified static optimization algorithmss\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified static optimization algorithmss ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithmss") OR ("modified objective optimization algorithm"))*.
