Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
network optimisation » network optimization
modified graining » modified caging
graining methods » learning methods, learning method, making methods
modified network » certified network, defined network, modified near

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified graining methods algorithm ) OR ( modified network optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified graining methods algorithm ) OR ( modified network optimisation algorithm ))*.
