Dear Dr. Norvig,

Recently I read AIMA and I'm sending a list of the errors I found
I hope it helps

1.Chapter 14, page 515, figure 14.14

replace

x,w <- Weighted-Sample(bn)

with
x,w <- Weighted-Sample(bn,e)

2. chapter 14, page 527, line 10

replace

T(Tall(Nate) /\ T(Heavy(Nate)) = 0.4

with

T(Tall(Nate) /\ Heavy(Nate)) = 0.4
3.chapter 15, page 545

replace

bk+1:t = BACKWARD(bk+2:t,ek+1:t)

with
bk+1:t = BACKWARD(bk+2:t,ek+1)
4.Appendix A, page 982

The typo is in the formula for F(x)
We can't integrate over variable x because x is the upper
boundary for the integral

5.chaprer 16 page 596

replace

U(x1,...,xn) = f[f1(x1),...,fn(xn) , ]

with

U(x1,...,xn) = f[f1(x1),...,fn(xn)] ,

6.Chapter 17 page 637, figure 17.11

The utility expectation for player O when E has a mixed
strategy should be -3*p + 4*(1-p) instead of 3*p + 4*(1-p)
In the second case the utility expectation for E when O has a
mixed strategy should be -3*q + 4*(1-q) instead of 3*q

+ 4*(1-q)

7.Chapter 18 page 669, line 5 from the bottom
replace

"Thus, the probability that it agrees with a given example is
at least"

with
"Thus, the probability that it agrees with a given example is
at most"

8.Chapter 23 page 837, figure 23.1

return sequence,best[i]

should be replaced with

return sequence,best[n]

because the overal sequence probability is accumulated in best
[n]

9.Chapter 24 page 869

In the formula of the Gaussian filter sigma ^ 2 should be
replaced with sigma or it should be placed under the square
