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)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"image 2_long algorithm" » "image colony algorithm" (Expand Search), "image making algorithm" (Expand Search), "image mining algorithm" (Expand Search), "image 1_long algorithm" (Expand Search), "image 2_an 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 ((("image 2_long algorithm") OR ("data modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"image 2_long algorithm\") OR (\"data modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( image 2_long algorithm ) OR ( data modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("image 2_long algorithm") OR ("data modeling algorithm"))))*.
