Perhaps you should try some spelling variations:
"algorithm both function" » "algorithm goa function" (Expand Search), "algorithm aoa function" (Expand Search)
"algorithm cost function" » "algorithm goa function" (Expand Search), "algorithm aoa function" (Expand Search)
"algorithm its function" » "algorithm _ function" (Expand Search), "algorithm fa function" (Expand Search), "algorithm goa function" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("algorithm both function") OR ("algorithm cost function"))) OR ("algorithm its function"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"algorithm both function\") OR (\"algorithm cost function\"))) OR (\"algorithm its function\"))*".
• Removing quotes may allow a broader search: (((( algorithm both function ) OR ( algorithm cost function ))) OR ( algorithm its function ))*.
