Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"presence data algorithms" » "presence art algorithms" (Expand Search), "presence all algorithms" (Expand Search), "presence both algorithms" (Expand Search), "prevalence data algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("presence data algorithms") OR ((("query processing algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"presence data algorithms\") OR (((\"query processing algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( presence data algorithms ) OR ((( query processing algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("presence data algorithms") OR ((("query processing algorithm") OR ("neural coding algorithm"))))*.
