Perhaps you should try some spelling variations:
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution algorithms"
"effective mapping methods algorithm" » "affective mapping methods algorithm", "effective reading methods algorithm", "effective making methods algorithm", "effective learning methods algorithm", "effective graining 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: (("effective mapping methods algorithm") or ("modified objective evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("effective mapping methods algorithm") OR ("modified objective evolution algorithm")).
• Removing quotes may allow a broader search: (( effective mapping methods algorithm ) or ( modified objective evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("effective mapping methods algorithm") or ("modified objective evolution algorithm"))*.
