I am a Phd student from Algeria, and I received an invitation to Review for the International Journal of Adaptive Control and Signal Processing. My Phd supervisor advised me to accept the invitation to review the paper, so I accepted the invitation.
Now from the title of the paper, it looks to be in the field that I am working in. However, when I accepted the invitation and they sent the manuscript to me, it is much more complicated than it looks from its title and touches on topics that I do not know.
What are the best responses should I give in the reply?
