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