Hi,
I have a program which is very similar to the 'aligning for a photo'
example. My 'people' are scenes in a narrative, each scene is a tuple
which describes a scene by type, start time and participants. A scene
might require precedent scenes, which have the participants in various
different configurations, to have occurred before. In my script,
Alignment is a list of integers which represent indexes to the actual
scnenes. The order in which the scenes should occur is the order of the
list. I am trying to order the scenes so that as many as possible of the
precedences are satisfied.
I have functions which create a tuple with 'wild-cards' and can then
match this tuple against actual scenes. So my current approach is to
loop through each item in 'Alignment', locating the corresponding scene
and building 'wild-card' tuples for any precedence required. I then
check each preceding item in Alignment to see if the corresponding scene
matches any of these tuples. Finally a successful match is converted to
a 1, unsuccessful to a 0.
In effect it's similar to aligning people for a photo so that each
person has preferences on who should be to the left of them in the line,
which may be none or more people.
I'm having enormous problems with my program, but if someone could
suggest how the photo example could be modified to add the 'to the right
of' preference, I might be able to convert that to suit my purposes.
Thank you in advance for any help
Regards
Mark
