Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
market estimation » market optimization, parameter estimation
modified passive » modified adaptive
passive solution » positive solutions, saline solution
modified market » modified male

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 passive solution algorithm ) OR ( modified market estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive solution algorithm ) OR ( modified market estimation algorithms ))*.
