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 large variation algorithm" » "modified large estimation algorithm", "modified large predation algorithm", "modified large estimation algorithms", "modified large evaluation algorithm", "modified male variation 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 ("modified large variation algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified large variation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified large variation algorithm"))*.
