Perhaps you should try some spelling variations:
"element mapping algorithms" » "element matching algorithms" (Expand Search), "element making algorithm" (Expand Search), "element pacing algorithms" (Expand Search), "elemental mapping algorithms" (Expand Search), "element modeling algorithms" (Expand Search), "argument mapping algorithms" (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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"element mapping algorithms\") OR (\"level coding algorithm\"))))~".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( element mapping algorithms ) OR ( level coding algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("element mapping algorithms") OR ("level coding algorithm"))))*.
