By the way, are we sure it is underestimation of the edges and corners ?
Rather than overestimation of the centre ?

I think they overestimate both the corners and the center, but they
overestimate the corners less. :-)
They will often force from the outside, even when an invasion is relatively
simple and the outside forcing stones aren't worth much. I can only call
that overestimating corner safety.
But at the same time, the center is given even greater priority, because
the playouts so often come back with a kill of would be invaders.
Crazy Stone seems to be ahead of the other bots in this.
My guess is that it's using simulation balancing in the playouts to
purposely degrade attacking moves.
Ajas' idea of biasing towards secure territory is a typical strong players
idea. But what does "secure" mean?
Maybe the idea Ingo brought up, to naively give corner and edge territory a
higher weight in the early stages of the game, is more promising. It feels
like a crutch, but when you have broken leg, a crutch is great.
