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