Perhaps you should try some spelling variations:
whale optimization » swarm optimization (Expand Search)
codon optimization » wolf optimization (Expand Search)
library based » laboratory based (Expand Search)
image whale » image scale (Expand Search)
based codon » based color (Expand Search), based cohort (Expand Search), based action (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: (( binary image whale optimization algorithm ) OR ( library based codon optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary image whale optimization algorithm ) OR ( library based codon optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary image whale optimization algorithm ) OR ( library based codon optimization algorithm ))*.
