Perhaps you should try some spelling variations:
"model using algorithms" » "model pacing algorithms" (Expand Search), "model nine algorithms" (Expand Search), "model sorting algorithms" (Expand Search)
"element mining algorithm" » "element finding algorithm" (Expand Search), "element making algorithm" (Expand Search), "element training algorithms" (Expand Search), "element mapping algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using 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: (("model using algorithms") OR ((("element mining algorithm") OR ("level coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"model using algorithms\") OR (((\"element mining algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( model using algorithms ) OR ((( element mining algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("model using algorithms") OR ((("element mining algorithm") OR ("level coding algorithm"))))*.
