Perhaps you should try some spelling variations:
"present routing algorithm" » "present modeling algorithm" (Expand Search), "present finding algorithm" (Expand Search), "present making algorithm" (Expand Search), "present during algorithm" (Expand Search), "present solution 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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (("relevant data algorithm") OR ((("present routing algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"present routing algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( present routing algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("present routing algorithm") OR ("level coding algorithm"))))*.
