Perhaps you should try some spelling variations:
"signal modeling algorithm" » "signal making algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search), "visual modelling algorithm" (Expand Search)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements custom algorithm" (Expand Search), "elements crcy 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 ("elements cscap algorithm"))) OR ("signal modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"elements cscap algorithm\"))) OR (\"signal modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( elements cscap algorithm ))) OR ( signal modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("elements cscap algorithm"))) OR ("signal modeling algorithm"))*.
