Perhaps you should try some spelling variations:
"algorithm python function" » "algorithm within function" (Expand Search), "algorithms within function" (Expand Search), "algorithm both function" (Expand Search), "algorithm protein function" (Expand Search)
"algorithm could function" » "algorithm models function" (Expand Search), "algorithm cell function" (Expand Search), "algorithm cells function" (Expand Search)
"algorithm where function" » "algorithm sphere function" (Expand Search), "algorithm gene function" (Expand Search), "algorithm wave function" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("algorithm could function") OR ((("algorithm python function") OR ("algorithm where function"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"algorithm could function\") OR (((\"algorithm python function\") OR (\"algorithm where function\"))))".
• Removing quotes may allow a broader search: (( algorithm could function ) OR ((( algorithm python function ) OR ( algorithm where function )))).
• Adding a wildcard symbol may retrieve word variants: (("algorithm could function") OR ((("algorithm python function") OR ("algorithm where function"))))*.
