Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("core control method algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( core control method algorithm ) or ( modified multiobjective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("core control method algorithm") or ("modified multiobjective optimizer algorithms"))*.
