Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified make optimization algorithms" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make optimized algorithms", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithm") or ("modified make optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithm") OR ("modified make optimization algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified make optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified make optimization algorithms"))*.
