Perhaps you should try some spelling variations:
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
bi1 optimisation » _ optimisation, _ optimization, qoe optimization
modified bi1 » modified _

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified charging solution algorithm ) OR ( modified bi1 optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified charging solution algorithm ) OR ( modified bi1 optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified charging solution algorithm ) OR ( modified bi1 optimisation algorithm ))*.
