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 model predicting algorithm" » "modified model predation algorithm", "modified model predators algorithm", "modified model splitting algorithm", "modified model predictive algorithm", "modified model reduction algorithm", "modified male predicting algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimisation algorithm") or ("modified model predicting algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("modified model predicting algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified model predicting algorithm ))*.
