Confirmed errors:


[10]  Figure 2-2;
Figure 2-2 shows only one scenario (that is one circle chasing one diamond).  The
paragraph following it refers to "the scenario on the left" (wherein the prey is
sitting still), and "the scenario on the right" (in which the prey is moving along
some arbitrary path over time).  Figure 2-2 only shows the first scenario.

(90-92)
Figures 5-4 and 5-5 are swapped (including the captions).


{152}  Example 8-4;

The first parameter to fi_GetData() needs closing quotation
marks.  In other words,

intelligence[kTroll]=fi_GetData("Troll Settings.txt,
                        "INTELLIGENCE");
strength[kTroll]=fi_GetData("Troll Settings.txt,
                     "STRENGTH");
speed[kTroll]=fi_GetData("Troll Settings.txt,
                   "SPEED");

should be:

intelligence[kTroll]=fi_GetData("Troll Settings.txt",
                        "INTELLIGENCE");
strength[kTroll]=fi_GetData("Troll Settings.txt",
                     "STRENGTH");
speed[kTroll]=fi_GetData("Troll Settings.txt",
                   "SPEED");



(171) in figure 9.3;
The text "Thisty" should be "Thirsty"


{188} Example code;
Fuzzy Logic problems, Chapter 10, are not in Examples download.


{249} 3rd paragraph, 4th sentence;
The text say "In Figure 13-1, C causes D and D causes E and F, but A and B cause C." However, there are no 
states named A to F in 13-1.

Figure 13-1 looks like this (more or less, as ASCII-images):

Trapped (T)


(353)  code sample;
Y += u.y;

The "Y" should be lowercased.
