Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"active reading methods algorithm" » "active learning methods algorithm", "active making methods algorithm", "active graining methods algorithm", "effective reading methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("active reading methods algorithm") or ("modified objective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("active reading methods algorithm") OR ("modified objective optimization algorithms"))*.
• Removing quotes may allow a broader search: (( active reading methods algorithm ) or ( modified objective optimization algorithms ))*.
