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