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)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (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 tree algorithms") OR ((("data modeling algorithm") OR ("image using algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tree algorithms\") OR (((\"data modeling algorithm\") OR (\"image using algorithms\"))))".
• Removing quotes may allow a broader search: (( element tree algorithms ) OR ((( data modeling algorithm ) OR ( image using algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element tree algorithms") OR ((("data modeling algorithm") OR ("image using algorithms"))))*.
