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 one algorithm" » "core using our algorithm", "core using _ algorithm", "core using mom algorithm", "code using one algorithm", "care nursing one algorithm", "core using open algorithm", "core using pre algorithm", "core using online 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 one algorithm") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"core using one algorithm\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( core using one algorithm ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core using one algorithm") OR ("modified multiobjective optimization algorithm"))*.
