Perhaps you should try some spelling variations:
"elemental mapping algorithm" » "elemental making algorithm" (Expand Search), "elemental mining algorithm" (Expand Search), "elemental learning algorithm" (Expand Search), "elements mapping algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element te algorithms" (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 ml algorithms") OR ((("elemental mapping algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ml algorithms\") OR (((\"elemental mapping algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element ml algorithms ) OR ((( elemental mapping algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ml algorithms") OR ((("elemental mapping algorithm") OR ("level coding algorithm"))))*.
