Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"core using rbf algorithm" » "core using _ algorithm", "core using mom algorithm", "core using our algorithm", "code using rbf algorithm", "care nursing rbf algorithm", "core using ibm algorithm", "core 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: (("core using rbf algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core using rbf algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( core using rbf algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core using rbf algorithm") or ("modified multiobjective optimization algorithm"))*.
