Perhaps you should try some spelling variations:
"image modeling algorithm" » "image making algorithm" (Expand Search), "age modeling algorithm" (Expand Search), "climate modeling algorithm" (Expand Search), "case modeling algorithm" (Expand Search)
"levels using algorithms" » "levels pacing algorithms" (Expand Search), "levels nine algorithms" (Expand Search), "levels sorting algorithms" (Expand Search), "level using algorithms" (Expand Search), "models using algorithms" (Expand Search), "cells using algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (("image modeling algorithm") OR ((("element data algorithm") OR ("levels using algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image modeling algorithm\") OR (((\"element data algorithm\") OR (\"levels using algorithms\"))))".
• Removing quotes may allow a broader search: (( image modeling algorithm ) OR ((( element data algorithm ) OR ( levels using algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image modeling algorithm") OR ((("element data algorithm") OR ("levels using algorithms"))))*.
