Perhaps you should try some spelling variations:
"element modelling algorithm" » "element scheduling algorithm" (Expand Search), "elements modelling algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"recent covid algorithm" » "recent cosine algorithm" (Expand Search), "recent mould algorithm" (Expand Search), "recent colony 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: (("recent covid algorithm") OR ((("element modelling algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"recent covid algorithm\") OR (((\"element modelling algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( recent covid algorithm ) OR ((( element modelling algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("recent covid algorithm") OR ((("element modelling algorithm") OR ("neural coding algorithm"))))*.
