Perhaps you should try some spelling variations:
"modified notion optimisation algorithmsss" » "modified notion optimisation algorithm", "modified notion optimization algorithms", "modified notion estimation algorithms", "modified network optimization algorithmsss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective 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: (("modified notion optimisation algorithmsss") OR ("modified objective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimisation algorithmsss\") OR (\"modified objective optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified notion optimisation algorithmsss ) OR ( modified objective optimization algorithm ))*.
