Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"verified network optimization algorithm" » "verified network optimization algorithms", "verified network estimation algorithm", "verified network estimation algorithms", "certified network optimization algorithm", "defined network optimization algorithm"

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