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