Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"model control methods algorithm" » "mode control methods algorithm", "order control methods algorithm", "model 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: (("model control methods algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("model control methods algorithm") OR ("modified multiobjective optimization algorithms"))*.
• Removing quotes may allow a broader search: (( model control methods algorithm ) or ( modified multiobjective optimization algorithms ))*.
