Perhaps you should try some spelling variations:
"algorithm cost function" » "algorithm goa function" (Expand Search), "algorithm aoa function" (Expand Search), "algorithm its function" (Expand Search)
"algorithm heat function" » "algorithm goa function" (Expand Search), "algorithm a function" (Expand Search), "algorithm aoa function" (Expand Search), "algorithm heart function" (Expand Search)
"algorithm fa function" » "algorithm _ function" (Expand Search), "algorithms a function" (Expand Search), "algorithms _ 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 cost function") OR ("algorithm heat function"))) OR ("algorithm fa function"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"algorithm cost function\") OR (\"algorithm heat function\"))) OR (\"algorithm fa function\"))".
• Removing quotes may allow a broader search: (((( algorithm cost function ) OR ( algorithm heat function ))) OR ( algorithm fa function )).
• Adding a wildcard symbol may retrieve word variants: (((("algorithm cost function") OR ("algorithm heat function"))) OR ("algorithm fa function"))*.
