Perhaps you should try some spelling variations:
whale optimization » swarm optimization (Expand Search)
cost optimization » dose optimization (Expand Search), robust optimization (Expand Search), codon optimization (Expand Search)
binary data » primary data (Expand Search), dietary data (Expand Search)
binary arm » binary pairs (Expand Search)
data whale » data where (Expand Search), data wales (Expand Search)
arm cost » arm most (Expand Search), from cost (Expand Search), a cost (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary arm cost optimization algorithm ) OR ( binary data whale optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary arm cost optimization algorithm ) OR ( binary data whale optimization algorithm ))*.
