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