Tutorial 10 Decision Blocks

[Hidemichi Yonezawa]

Hi,

In the tutorial, the Step3 of the decision block is

voltage > 2.volts

However, there is no choice like that.
The default is

voltage > 120

I am using just the default.
Is it fine? Also, if someone explain of this step3 of the
decision block, I would really appreciate it.

Sincerely,
Hidemichi

Step 3 provides a list of some example expressions for the agent to
evaluate.  What shows up in Step 3 is not actually used in the decision
block, only what shows up in Step 4.  If you select an item in Step 3 it
is copied to Step 4 and you may edit Step 4 independenly of Step 3.  In
the Ch 10 of the tutorial, the example in Step 3 is used to illustrate
comparing an agent attribute using the "greater than" operator with a
constant value (watchedNode.pressure < 200).

As a side node, the SI units can be used to compare Amount properties,
as long as the units can be compared in a meaningful way, ie you may
compare "voltage > 2.volts" as long as the voltage propery can be
converted to volts, but not to say another unit type such as length.

Hi Eric,

Thanks. I got it.

I have another question. Is there any tutorial or some material
other than that initial tutorial and Boids tutorial for learning Repast S?
Although I did both, I am not enough familiar to use Repast to make
a model at all. I know about the course at the conference in Virginia.
However, I don't think I can go there. Also, I've heard the course by Argonne
lab would be next year.
If anyone knows something, it would be really helpful.
Thanks in advance.
