Perhaps you should try some spelling variations:
"model testing algorithm" » "model twisting algorithm" (Expand Search), "model hastings algorithm" (Expand Search), "model boosting algorithm" (Expand Search), "model fitting algorithm" (Expand Search), "model test algorithm" (Expand Search)
"elements custom algorithm" » "elements fusion algorithm" (Expand Search), "elements control algorithm" (Expand Search), "elements lasso algorithm" (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: (((("elements custom algorithm") OR ("model testing algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements custom algorithm\") OR (\"model testing algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( elements custom algorithm ) OR ( model testing algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements custom algorithm") OR ("model testing algorithm"))) OR ("neural coding algorithm"))*.
