General Clarifications
April 5
Update to mark distribution for A3 Part 2: To better
reflect the level of effort required for these questions and to
facilitate the allocation of part marks, A3-Part2-Question2
is now worth 16 marks (rather than 10) and A3-Part2-Question3
is worth 14 marks (rather than 10). This causes A3-Part2
to now be marked out of 50 marks rather than 40 marks. Note
the percentage of your total grade made up by A3-Part2 is unchanged.
April 5
We have been receiving a number of questions regarding
the difference between STRIPS and ADL. ADL ("Action Description
Language") is more expressive than STRIPS and as such supports the expression of more complex action preconditions and action effects. See Slides 50-60 of the Planning slide deck for a description of STRIPS. See Slides 116-121 of the same slide deck for a description of ADL. You can also
find a description of both on wikipedia and in other reference
material.

Just to clarify, you are supposed to come up with your own numbers for the conditional probability tables. The probability table for P(Signature|Fraud) is just an example. You CAN use it if you wish, but do not have to.
April 2
There are now two tutorials for PDDL available on the A3 page.

Multiple rovers can be at the same location at the same time.
There is no limit to the rovers special ability (sampling rock, soil, image). They may not be equiped to sample anything at all.
