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