Perhaps you should try some spelling variations:
"experiments forest algorithm" » "experiments firefly algorithm" (Expand Search), "experimental forest algorithm" (Expand Search)
"tests using algorithms" » "tests cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling 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: (((("experiments forest algorithm") OR ("tests using algorithms"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experiments forest algorithm\") OR (\"tests using algorithms\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experiments forest algorithm ) OR ( tests using algorithms ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experiments forest algorithm") OR ("tests using algorithms"))) OR ("neural coding algorithm"))*.
