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"
"modified adam approximation algorithm" » "modified adam approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"

You may be able to get more results by adjusting your search query.

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