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 saline solution algorithm" » "modified saline evolution algorithm", "modified saline convolution algorithms", "modified saline evolutionary algorithm", "modified caging solution algorithm", "modified male solution algorithm", "modified passive solution 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 saline solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic optimization algorithms") OR ("modified saline solution algorithm"))*.
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithms ) or ( modified saline solution algorithm ))*.
