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 quadratic estimation algorithms" » "modified quadratic estimation algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quantile estimation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quadratic estimation algorithms") or ("modified static optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic estimation algorithms") OR ("modified static optimization algorithm")).
• Removing quotes may allow a broader search: (( modified quadratic estimation algorithms ) or ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic estimation algorithms") or ("modified static optimization algorithm"))*.
