Perhaps you should try some spelling variations:
"stool modeling algorithm" » "stool making algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 ("element method algorithm"))) OR ("stool modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element method algorithm\"))) OR (\"stool modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element method algorithm ))) OR ( stool modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element method algorithm"))) OR ("stool modeling algorithm"))*.
