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"
"code learning predation algorithm" » "code learning predators algorithm", "code learning estimation algorithm", "code learning prediction algorithm", "code learning emotion algorithm", "how learning predation 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 multiobjective optimisation algorithm") OR ("code learning predation algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( code learning predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("code learning predation algorithm"))*.
