Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"boiler using rbf algorithm" » "boiler using _ algorithm", "boiler using mom algorithm", "boiler using our algorithm", "powder using rbf algorithm", "boiler using ibm algorithm", "boiler 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: (("boiler using rbf algorithm") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"boiler using rbf algorithm\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( boiler using rbf algorithm ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("boiler using rbf algorithm") OR ("modified multiobjective optimization algorithm"))*.
