Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"mapping learning evolution algorithm" » "mapping learning solution algorithm", "mapping learning evolutionary algorithm", "mapping learning convolution algorithms", "mapping learning convolution algorithm", "mapping learning emotion algorithm", "machine learning evolution algorithm", "enabling learning 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: (("mapping learning evolution algorithm") OR ("modified objective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning evolution algorithm\") OR (\"modified objective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( mapping learning evolution algorithm ) OR ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning evolution algorithm") OR ("modified objective estimation algorithms"))*.
