Perhaps you should try some spelling variations:
"spatial mapping algorithm" » "spatial making algorithm" (Expand Search), "spatial mining algorithm" (Expand Search), "spatial learning algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search), "spatial planning algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element ipca algorithm" » "element wgcna algorithm" (Expand Search), "element cscap algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element data 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 ipca algorithm") OR ((("spatial mapping algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ipca algorithm\") OR (((\"spatial mapping algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element ipca algorithm ) OR ((( spatial mapping algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ipca algorithm") OR ((("spatial mapping algorithm") OR ("neural coding algorithm"))))*.
