Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
near optimization » network optimization, stage optimization, _ optimization
machine graining » machine learning
graining methods » learning methods, learning method, making methods
modified near » modified seird, modified adam

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( machine graining methods algorithm ) OR ( modified near optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( machine graining methods algorithm ) OR ( modified near optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( machine graining methods algorithm ) OR ( modified near optimization algorithm ))*.
