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