Perhaps you should try some spelling variations:
process optimization » model optimization (Expand Search)
design optimization » bayesian optimization (Expand Search)
primary wave » primary care (Expand Search), primary case (Expand Search), primary cause (Expand Search)
ramp process » jump process (Expand Search), acp process (Expand Search), creep process (Expand Search)
wave design » game design (Expand Search), case design (Expand Search), based design (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: (( primary wave design optimization algorithm ) OR ( binary ramp process optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( primary wave design optimization algorithm ) OR ( binary ramp process optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( primary wave design optimization algorithm ) OR ( binary ramp process optimization algorithm ))*.
