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"
"modified positive solutions algorithm" » "modified positive solution algorithm", "modified positive evolution algorithm", "modified positive evolutionary algorithm", "modified passive solutions algorithm", "modified adaptive solutions 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 positive solutions algorithm") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified positive solutions algorithm\") OR (\"modified objective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified positive solutions algorithm ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified positive solutions algorithm") OR ("modified objective optimisation algorithm"))*.
