Perhaps you should try some spelling variations:
"made routing algorithms" » "made routing algorithm" (Expand Search), "made sorting algorithms" (Expand Search), "made using algorithms" (Expand Search), "made during algorithms" (Expand Search), "call routing algorithms" (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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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 using algorithm") OR ("made routing algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data using algorithm\") OR (\"made routing algorithms\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data using algorithm ) OR ( made routing algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data using algorithm") OR ("made routing algorithms"))))*.
