Perhaps you should try some spelling variations:
"modified choosing optimization algorithms" » "modified choosing optimisation algorithm", "modified choosing estimation algorithms", "modified choosing estimation algorithm", "modified choosing optimisation algorithms", "modified choosing estimation algorithmss", "modified staffing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimization algorithms"
"modified static optimization algorithm" » "modified static optimisation algorithm", "modified static estimation algorithm", "modified static estimation algorithms", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified choosing optimization algorithms") OR ("modified static optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified choosing optimization algorithms\") OR (\"modified static optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified choosing optimization algorithms ) OR ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified choosing optimization algorithms") OR ("modified static optimization algorithm"))*.
