Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimisation algorithms", "modified static estimation algorithmss", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"modified df optimization algorithm" » "modified df optimisation algorithm", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified adam optimization algorithm", "modified bi1 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 df optimization algorithm") OR ("modified static optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df optimization algorithm\") OR (\"modified static optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified df optimization algorithm ) OR ( modified static optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df optimization algorithm") OR ("modified static optimization algorithms"))*.
