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