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