Perhaps you should try some spelling variations:
"image 3_modeling algorithm" » "image sampling algorithm" (Expand Search), "image 3_making algorithm" (Expand Search), "image 3_mendelian algorithm" (Expand Search), "image 3_mapping algorithm" (Expand Search), "file 3_modeling algorithm" (Expand Search)
"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)

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 modeling algorithm") OR ("image 3_modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data modeling algorithm\") OR (\"image 3_modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data modeling algorithm ) OR ( image 3_modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data modeling algorithm") OR ("image 3_modeling algorithm"))))*.
