Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"code control method algorithm" » "code control mom algorithm", "code control methods algorithm", "mode control method algorithm", "case control method algorithm", "order control method algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithms\") OR (\"code control method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) OR ( code control method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") OR ("code control method algorithm"))*.
