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 using algorithms" » "image pacing algorithms" (Expand Search), "image nine algorithms" (Expand Search), "image sorting algorithms" (Expand Search), "images using algorithms" (Expand Search), "made using algorithms" (Expand Search), "imaging using algorithms" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related 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 based algorithm") OR ((("data modeling algorithm") OR ("image using algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements based algorithm\") OR (((\"data modeling algorithm\") OR (\"image using algorithms\"))))".
• Removing quotes may allow a broader search: (( elements based algorithm ) OR ((( data modeling algorithm ) OR ( image using algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("elements based algorithm") OR ((("data modeling algorithm") OR ("image using algorithms"))))*.
