Perhaps you should try some spelling variations:
cross optimization » cost optimization (Expand Search), process optimization (Expand Search), stress optimization (Expand Search)
codon optimization » wolf optimization (Expand Search)
binary mask » binary image (Expand Search)
binary base » ciliary base (Expand Search), binary image (Expand Search)
mask cross » mass across (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 mask cross optimization algorithm ) OR ( binary base codon optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary mask cross optimization algorithm ) OR ( binary base codon optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary mask cross optimization algorithm ) OR ( binary base codon optimization algorithm ))*.
