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