Perhaps you should try some spelling variations:
"afm modeling algorithm" » "afm making algorithm" (Expand Search), "a modeling algorithm" (Expand Search), "ann modeling algorithm" (Expand Search), "dft modeling algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural finding algorithm" (Expand Search), "neural routing algorithm" (Expand Search)
"element box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements box 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 box algorithm") OR ((("afm modeling algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element box algorithm\") OR (((\"afm modeling algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element box algorithm ) OR ((( afm modeling algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element box algorithm") OR ((("afm modeling algorithm") OR ("neural coding algorithm"))))*.
