bring your presentations on a memory stick..

Folks

Bring your slides for today on a memory stick. We will load them on
the class computer in the beginning so the presentations can be
streamlined.

Indeed, Hector took the picture. "Optimizing the Steel Plate Storage
Yard Crane Selection Problem", ICAPS 2007 (DC Poster). I believe a
short paper version exists in the proceedings somewhere...

A related journal article on blockstacking (no joke, that's one of the
keywords):

This poster is on a domain which is very blocksworld-ish. Also has
towers-of-hanois-ish in that there is no table of infinite capacity;
only stacks. However, there appear to be no stacking restrictions
(objects don't have different weights or sizes that require sorted
stacks).

The steel plates *do* have individual names which distinguish them, a
highly important technical point (in the comparison with blocksworld).

The goal state is not a stacking configuration; the goal is to
minimize movement over time (as I understand it), each day one is to
deliver certain plates to a conveyer at the far right of the
coordinate system. One has a nominal schedule when plates will
arrive and when they will be requested, allowing one to subgoal on
intermediate stacking configurations (or rather a sequence of stacking
configurations) which minimizes movements while achieving those
schedules. (and then there is some online planning for each day as
requests and supplies deviate from nominal).

So many interesting components that bar applying FF directly to the
problem...but....a big core part of the technical problem *is*
blocksworld. On ~1000 "blocks", in case anyone likes to think of
planning + scaling.

Correction for a homework 2 problem..

In Question 1, where I say "Y can start at least 1 unit or at most 2
units after X" , please replace the "or" with an "and" (the "or"
constraint becomes a non-constraint since you will basically have two
constraints [-inf 2] [1 +inf] which is equivalent to [-inf +inf]

Assistance or distraction?

The agent is quite intelligent and his behavior is close to the optimal, he is doing well. The assistant learns the agent’s goal and behavior, and starts to act. The agent notices that the world became friendlier, but different. It is time for active exploration (which is expensive) by the agent. The exploration changes goal distribution completely; the assistant distorts the world by trying to achieve wrong goals. After awhile the assistant stops to act, the agent finishes exploration (suspecting he had a glitch); and they are back to the old world.
It seems that assistance works, if an assistant much smarter than an agent; and an agent accepting the world as it appears, without trying to learn it.

*Important*: Format of the class of 4/29--you will do short presentations of your project findings

Folks:

For 4/29 (i.e., next Tuesday's class), I will take about 10 min to
do a "here is what we did" spiel. The rest of the class will be spent
with
each of you making a 5-min presentation about your project findings.
This will also serve as a quick summary of your report (that you will
also
bring to the class that day). Ideally, you make this presentation as
an advertisement to draw people to read your report (you will also
give me electronic--
pdf and ppt versions) of the report and talk.

I think there is a reasonable amount of diversity in the projects that
it is worth everyone hearing summaries of what others did).

thanks
