Perhaps you should try some spelling variations:
"image 1_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 1_resting algorithm" (Expand Search), "image 1_reducing algorithm" (Expand Search), "image 1_using algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 pass algorithm") OR ((("image 1_routing algorithm") OR ("data using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element pass algorithm\") OR (((\"image 1_routing algorithm\") OR (\"data using algorithm\"))))".
• Removing quotes may allow a broader search: (( element pass algorithm ) OR ((( image 1_routing algorithm ) OR ( data using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element pass algorithm") OR ((("image 1_routing algorithm") OR ("data using algorithm"))))*.
