Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified charging » modified caging, modified carbon
charging solution » charging station

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