Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"core control method algorithm" » "core control mom algorithm", "core control methods algorithm", "case control method algorithm", "mode control method algorithm", "torque control method 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 control method algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core control method algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( core control method algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core control method algorithm") or ("modified multiobjective optimization algorithm"))*.
