Perhaps you should try some spelling variations:
"element custom algorithm" » "element control algorithm" (Expand Search), "element auction algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements custom algorithm" (Expand Search)
"implement making algorithm" » "implement cosine algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level colony algorithm" (Expand Search), "level scheduling algorithm" (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: (("element custom algorithm") OR ((("implement making algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element custom algorithm\") OR (((\"implement making algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element custom algorithm ) OR ((( implement making algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element custom algorithm") OR ((("implement making algorithm") OR ("level coding algorithm"))))*.
