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 based function" » "algorithm based functional" (Expand Search), "algorithm basis function" (Expand Search), "algorithm basis functions" (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 a function") OR ("algorithm based function"))) OR ("algorithm python function"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"algorithm a function\") OR (\"algorithm based function\"))) OR (\"algorithm python function\"))".
• Removing quotes may allow a broader search: (((( algorithm a function ) OR ( algorithm based function ))) OR ( algorithm python function )).
• Adding a wildcard symbol may retrieve word variants: (((("algorithm a function") OR ("algorithm based function"))) OR ("algorithm python function"))*.
