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"
"model using rbf algorithm" » "model using _ algorithm", "model using mom algorithm", "model using our algorithm", "code using rbf algorithm", "models nursing rbf algorithm", "powder using rbf algorithm", "model using ibm algorithm", "model using raw algorithm"

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

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