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