Perhaps you should try some spelling variations:
"cloud modeling algorithm" » "cloud making algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "cloud model algorithm" (Expand Search), "flow modeling 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)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement 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: (((("cloud modeling algorithm") OR ("data sorting algorithms"))) OR ("movement data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cloud modeling algorithm\") OR (\"data sorting algorithms\"))) OR (\"movement data algorithm\"))".
• Removing quotes may allow a broader search: (((( cloud modeling algorithm ) OR ( data sorting algorithms ))) OR ( movement data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("cloud modeling algorithm") OR ("data sorting algorithms"))) OR ("movement data algorithm"))*.
