Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing 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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method 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 method algorithm") OR ((("data modelling algorithm") OR ("image 2_using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data modelling algorithm\") OR (\"image 2_using algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data modelling algorithm ) OR ( image 2_using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data modelling algorithm") OR ("image 2_using algorithm"))))*.
