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 using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement 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 using algorithm") OR ("flood modeling algorithm"))) OR ("settlement data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"flood modeling algorithm\"))) OR (\"settlement data algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( flood modeling algorithm ))) OR ( settlement data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("flood modeling algorithm"))) OR ("settlement data algorithm"))*.
