Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective optimized algorithms", "modified multiobjective optimization algorithms"
"model learning estimation algorithm" » "model learning emotion algorithm", "model lighting estimation algorithm", "mobile learning estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("model learning estimation algorithm") OR ("modified objective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model learning estimation algorithm\") OR (\"modified objective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( model learning estimation algorithm ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("model learning estimation algorithm") OR ("modified objective optimization algorithms"))*.
