Perhaps you should try some spelling variations:
"image routing algorithm" » "image modeling algorithm" (Expand Search), "image finding algorithm" (Expand Search), "image making algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 3_using algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element mesh algorithms" » "element best algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element best algorithm" (Expand Search), "elements mges algorithms" (Expand Search), "element te algorithms" (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 ("element mesh algorithms"))) OR ("image routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element mesh algorithms\"))) OR (\"image routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element mesh algorithms ))) OR ( image routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element mesh algorithms"))) OR ("image routing algorithm"))*.
