Talk:Hamilton-Jacobi-Bellman equation
From Wikipedia, the free encyclopedia
Um, I don't think the Hamilton-Jacobi-Bellman equation is the Hamilton-Jacobi equation anymore than let's say Shannon information is the thermodynamic entropy. Phys 02:57, 15 Aug 2004 (UTC)
Phys is right. There is some mixing together here of Hamilton-Jacobi-Bellman and Hamilton-Jacobi, of Optimal Control and Physics. The result is confusing. I will rewrite from the point of view of O.C. only. Someone else can add the relation to physics and to the pre-Bellman work. Encyclops July 2005
[edit] Bracket notation
Is there a reason for using the notation 
to denote inner product here? I'd prefer ordinary matrix notation: aTb. The latter is less confusing, since it can't be confused with other variations of scalar product, such as

aTb is very clear. But when a and b are somewhat messy expressions it becomes less readable. In our case what would we have 
? I don't know if I like it or not. Encyclops 00:23, 15 June 2006 (UTC)
