Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
notion estimation » motion estimation
co evolution » _ evolution
modified co » modified _, modified df, modified orca

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 co evolution algorithm ) OR ( modified notion estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified co evolution algorithm ) OR ( modified notion estimation algorithms ))*.
