Perhaps you should try some spelling variations:
action optimization » reaction optimization (Expand Search), function optimization (Expand Search), codon optimization (Expand Search)
binary change » binary image (Expand Search)
change action » change detection (Expand Search), change education (Expand Search)
binary mask » binary image (Expand Search)
mask global » major global (Expand Search), based global (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 change action optimization algorithm ) OR ( binary mask global optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary change action optimization algorithm ) OR ( binary mask global optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary change action optimization algorithm ) OR ( binary mask global optimization algorithm ))*.
