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