Perhaps you should try some spelling variations:
"algorithm spread function" » "algorithm survey function" (Expand Search), "algorithm sma function" (Expand Search)
"algorithm protein function" » "algorithm protein glycation" (Expand Search)
"algorithm co function" » "algorithm goa function" (Expand Search), "algorithm aoa function" (Expand Search), "algorithm _ function" (Expand Search), "algorithm cost 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 spread function") OR ("algorithm co function"))) OR ("algorithm protein function"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"algorithm spread function\") OR (\"algorithm co function\"))) OR (\"algorithm protein function\"))*".
• Removing quotes may allow a broader search: (((( algorithm spread function ) OR ( algorithm co function ))) OR ( algorithm protein function ))*.
