Perhaps you should try some spelling variations:
"elements routing algorithm" » "elements modeling algorithm" (Expand Search), "elements finding algorithm" (Expand Search), "elements making algorithm" (Expand Search), "elements during algorithm" (Expand Search), "element bonding algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element g algorithm" (Expand Search), "element data 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 routing algorithm") OR ("element te algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements routing algorithm\") OR (\"element te algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements routing algorithm ) OR ( element te algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements routing algorithm") OR ("element te algorithm"))) OR ("level coding algorithm"))*.
