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 routing algorithm" » "image finding algorithm" (Expand Search), "image making algorithm" (Expand Search), "image clustering algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 3_using algorithm" (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: (("element data algorithms") OR ((("based modeling algorithm") OR ("image routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element data algorithms\") OR (((\"based modeling algorithm\") OR (\"image routing algorithm\"))))".
• Removing quotes may allow a broader search: (( element data algorithms ) OR ((( based modeling algorithm ) OR ( image routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element data algorithms") OR ((("based modeling algorithm") OR ("image routing algorithm"))))*.
