Perhaps you should try some spelling variations:
"modified quadratic optimization algorithms" » "modified quadratic optimisation algorithm", "modified quadratic estimation algorithms", "modified quadratic estimation algorithm", "modified static optimization algorithms", "modified quadratic optimisation algorithms", "modified quadratic estimation algorithmss"
"modified allocation optimization algorithm" » "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified allocation estimation algorithms", "modified location 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 quadratic optimization algorithms") or ("modified allocation optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic optimization algorithms") OR ("modified allocation optimization algorithm")).
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithms ) or ( modified allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic optimization algorithms") or ("modified allocation optimization algorithm"))*.
