Perhaps you should try some spelling variations:
activation algorithm » estimation algorithm, estimation algorithms, optimisation algorithm
objective solution » objective evolutionary, objective allocation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
thermal activation » chemical activation, thermal oxidation

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