Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"pooled routing algorithm" » "pooled finding algorithm" (Expand Search), "pooled making algorithm" (Expand Search), "pooled clustering algorithm" (Expand Search), "pooled using 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)

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 modeling algorithm") OR ("pooled routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data modeling algorithm\") OR (\"pooled routing algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data modeling algorithm ) OR ( pooled routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data modeling algorithm") OR ("pooled routing algorithm"))))*.
