Perhaps you should try some spelling variations:
"space modeling algorithm" » "space making algorithm" (Expand Search), "space model algorithm" (Expand Search), "space models algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"deep clustering algorithm" » "cell clustering algorithm" (Expand Search), "re clustering algorithm" (Expand Search), "gene clustering algorithm" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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: (((("deep clustering algorithm") OR ("space modeling algorithm"))) OR ("element data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"deep clustering algorithm\") OR (\"space modeling algorithm\"))) OR (\"element data algorithms\"))".
• Removing quotes may allow a broader search: (((( deep clustering algorithm ) OR ( space modeling algorithm ))) OR ( element data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("deep clustering algorithm") OR ("space modeling algorithm"))) OR ("element data algorithms"))*.
