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