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)
"image 2_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements cnn 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 cnn algorithm") OR ((("image 2_using algorithm") OR ("data modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cnn algorithm\") OR (((\"image 2_using algorithm\") OR (\"data modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element cnn algorithm ) OR ((( image 2_using algorithm ) OR ( data modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cnn algorithm") OR ((("image 2_using algorithm") OR ("data modeling algorithm"))))*.
