Perhaps you should try some spelling variations:
"modified quadratic optimization algorithms" » "modified quadratic optimisation algorithm", "modified quadratic estimation algorithms", "modified quadratic estimation algorithm", "modified quadratic optimisation algorithms", "modified quadratic estimation algorithmss"
"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.

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