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