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