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