Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified based evolution algorithm" » "modified based solution algorithm", "modified based evolutionary algorithm", "modified based convolution algorithms", "modified based evaluation algorithm", "modified based solutions algorithm", "modified sales evolution algorithm", "modified male evolution algorithm"

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

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