Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"effective reading methods algorithm" » "effective gradient methods algorithm", "active reading methods algorithm", "effective learning methods algorithm", "effective making methods algorithm", "effective graining methods 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: (("modified multiobjective estimation algorithm") OR ("effective reading methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( effective reading methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("effective reading methods algorithm"))*.
