Perhaps you should try some spelling variations:
"implement modeling algorithm" » "element modeling algorithm" (Expand Search), "element modelling algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level routing algorithm" (Expand Search), "level according algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level using algorithm" (Expand Search)
"element cc3d algorithm" » "element cscap algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element wold algorithm" (Expand Search), "elements cc3d 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 cc3d algorithm") OR ((("implement modeling algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cc3d algorithm\") OR (((\"implement modeling algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element cc3d algorithm ) OR ((( implement modeling algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cc3d algorithm") OR ((("implement modeling algorithm") OR ("level coding algorithm"))))*.
