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"
"mobile learning predation algorithm" » "mobile learning predators algorithm", "mobile learning estimation algorithm", "mobile learning prediction algorithm", "mobile learning emotion algorithm", "machine learning predation 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: (("mobile learning predation algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mobile learning predation algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( mobile learning predation algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mobile learning predation algorithm") or ("modified multiobjective optimisation algorithm"))*.
