Perhaps you should try some spelling variations:
"data models algorithm" » "data mould algorithm" (Expand Search), "data deer algorithm" (Expand Search)
"table 1_decoding algorithm" » "stable 1_decoding algorithm" (Expand Search), "tables 1_decoding algorithm" (Expand Search), "able 1_decoding algorithm" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated 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: (((("table 1_decoding algorithm") OR ("data models algorithm"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"table 1_decoding algorithm\") OR (\"data models algorithm\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( table 1_decoding algorithm ) OR ( data models algorithm ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("table 1_decoding algorithm") OR ("data models algorithm"))) OR ("element update algorithm"))*.
