Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static optimized algorithms", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"defined network estimation algorithm" » "defined network optimization algorithm", "designed network estimation algorithm"

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

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