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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive optimization algorithms ) or ( modified charging solution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive optimization algorithms ) OR ( modified charging solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive optimization algorithms ) or ( modified charging solution algorithm ))*.
