Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
objective estimation » objective optimization, objective allocation
objective solution » objective evolutionary, objective allocation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm

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