I want to know about monotonous queue. I google it, but found nothing(may be i'm not good at searching!). :( Can any one describe it or give me some idea and information about it? It will be really appreciable. Thanks in advance. :)

It really sounds like it's just a queue whose items form a monotonous sequence. Maybe you have more precise questions?
I don't know too much about it, but someone calls it convex-hull trick or queue dp. It reduce the complexity of dp. Sorry for inconvenience.
If it's also called convex hull trick, it's probably this:

Thank you for your response. :)
