Perhaps you should try some spelling variations:
structure optimization » structural optimization (Expand Search), structure determination (Expand Search)
dose optimization » based optimization (Expand Search), model optimization (Expand Search), wolf optimization (Expand Search)
theme structure » tree structure (Expand Search), thermal structure (Expand Search), gene structure (Expand Search)
binary same » binary image (Expand Search)
same dose » same case (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 theme structure optimization algorithm ) OR ( binary same dose optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary theme structure optimization algorithm ) OR ( binary same dose optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary theme structure optimization algorithm ) OR ( binary same dose optimization algorithm ))*.
