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)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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: (("element method algorithm") OR ((("data finding algorithm") OR ("flood modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data finding algorithm\") OR (\"flood modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data finding algorithm ) OR ( flood modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data finding algorithm") OR ("flood modeling algorithm"))))*.
