Chapter 2:
On page 68, alignment of the following equations in Table 2.8 were as follows:
s 0 = ∑ j ∈ P λ j s j
and the direction
d B = −∑ j ∈ P λ j h j, where h j = A B −1 A . j.
It should be as follows:
s 0 = ∑ j ∈ P λ j s j
and the direction
d B = −∑ j ∈ P λ j h j, where h j = A B −1 A . j.
And
if d B ≥ 0 then
if s 0 = 0 then STOP. The LP problem is optimal.
else
choose the leaving variable x B[r] = x k using the following relation:
\(a = \frac{x_{B[r]}} {-d_{B[r]}} =\min \left \{ \frac{x_{B[i]}} {-d_{B[i]}}: d_{B[i]} < 0\right \},i = 1,2,\cdots \,,m\)
if a = ∞, the LP problem is unbounded.
It should be as follows:
if d B ≥ 0 then
if s 0 = 0 then STOP. The LP problem is optimal.

Chapter 4:
On page 211, 15th line from top, the sentence reads:
The column “Total size reduction” in Table 4.2 is calculated as follows: − (m new + n new − m − n)∕((m + n).

Chapter 8:
On page 345, 7th line from bottom, the sentence reads:
There are elements in vector h 1 that are greater than 0, so we perform the minimum ratio test (where the letter x is used below to represent that h i l ≤ 0, therefore \(\frac{x_{B[i]}} {h_{il}}\) is not defined):

Chapter 10:
On page 439, alignment of the following equation in Table 10.1 was as follows:
s 0 = ∑ j ∈ P λ j s j
and the direction
\(d_{B} = -\sum _{j\in P}\lambda _{j}h_{j}\), where \(h_{j} = A_{B}^{-1}A_{.j}\).
Step 2.1. (Test of Optimality).
if P = ∅ then STOP. (LP.1) is optimal.

if d B ≥ 0 then
if s 0 = 0 then STOP. (LP.1) is optimal.
