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)
"data sorting algorithms" » "data routing algorithm" (Expand Search), "data learning algorithms" (Expand Search), "data working algorithms" (Expand Search), "data supporting algorithms" (Expand Search), "data settings algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("signal modeling algorithm") OR ("data sorting algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"signal modeling algorithm\") OR (\"data sorting algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( signal modeling algorithm ) OR ( data sorting algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("signal modeling algorithm") OR ("data sorting algorithms"))) OR ("element method algorithm"))*.
