Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based 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 data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data 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: (((("based modeling algorithm") OR ("image using algorithms"))) OR ("element data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"based modeling algorithm\") OR (\"image using algorithms\"))) OR (\"element data algorithms\"))".
• Removing quotes may allow a broader search: (((( based modeling algorithm ) OR ( image using algorithms ))) OR ( element data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("based modeling algorithm") OR ("image using algorithms"))) OR ("element data algorithms"))*.
