## Chapter 10

• pg 265, fig 10.2: nodes labeled C, AT, GT, TA, TG, AAA, AGA and AGG should be shaded gray. Also, extensions of an infrequent pattern are not shown.

• pg 311, table 12.11: conv should be $$\infty$$ for row 1, since conf is 1

• pg 311, table 12.12: conv should be $$\infty$$ for rows 1 and 3, since conf is 1

## Chapter 15

• pg 377, Algorithm 15.1, Line 17: if $$\mathbf{y} \in Core$$ should be if $$\mathbf{y} \in Core$$ and $$id(\mathbf{y}) = \emptyset$$

This will prevent an infinite loop.
