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 pre function" » "algorithm where function" (Expand Search), "algorithm used function" (Expand Search), "algorithm from function" (Expand Search), "algorithm spread function" (Expand Search), "algorithm sphere function" (Expand Search), "algorithm three function" (Expand Search)
"algorithm a function" » "algorithm _ function" (Expand Search), "algorithm b function" (Expand Search), "algorithms _ 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 python function") OR ("algorithm a function"))) OR ("algorithm pre function"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"algorithm python function\") OR (\"algorithm a function\"))) OR (\"algorithm pre function\"))".
• Removing quotes may allow a broader search: (((( algorithm python function ) OR ( algorithm a function ))) OR ( algorithm pre function )).
• Adding a wildcard symbol may retrieve word variants: (((("algorithm python function") OR ("algorithm a function"))) OR ("algorithm pre function"))*.
