Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"adaptive control methods algorithm" » "adaptive 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: (("adaptive control methods algorithm") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( adaptive control methods algorithm ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("adaptive control methods algorithm") or ("modified multiobjective optimization algorithms"))*.
