Optimizing action combiner (for IRC bots)

modecombiner is a generic three-input logical expression optimizer, designed to distribute IRC operative actions to agents on various channels.
It takes a list of agents, list of channels each agent is on, list of actions and list of channels each action affects.
It produces a list of operations for each agent, to submit the wanted operations. It tries to produce the smallest list of operations to do the job, utilizing the necessary number of agents.
It also takes the priorities for each agent, and picks the ones who are most eager to do the job.

Usage: modecombiner [--notest] <agentdef> [<...>] /<op> [<opdef> [<...>]]

	--notest disables combining parameter limits.
	agentdef is: <nick>[:<load>[:<reliability>[:<hostload>]]] <channellist>
	channellist is: "<chan> [<...>]"
	For op='M', opdef is: <modestring>
	For op='K', opdef is: <kickstring>
	For op='T', opdef is: <topicstring>
	For op='G', opdef is: <msgstring>
	For op='N', opdef is: <noticestring>
	For op='Q', opdef is: <whoisstring>
	For op='O', opdef is: <functionstring>
	modestring is: "<chans> <modes> [<parameter> [<...>]]"
	kickstring is: "<chans> <nicks> <text>"
	topicstring, msgstring and noticestring are: "<chans> <text>"
	whoisstring is: "<nicks>"
	functionstring is: "<chan> <function> [<parameters> [<...>]]"
	chans is: <chan>[,<chan>[<...>]]
	nicks is: <nick>[,<nick>[<...>]]
	modes is a combination of alphabets and +/- signs.
	load is an unsigned integer, describing the load the agent has.
	reliability is an unsigned integer, bigger value meaning more reliable.
	hostload is an unsigned integer, used in functionstring; means host load.
		reliability value is used if two agents have equal chance otherwise.
Output consists of lines of following format:
	<op> <nick> <command>
	op=W is a special case: it means there is no agent
	able to do the job for the particular channel.
	op=O is handled specially (no grouping happens).

Running:

  modecombiner \
    Agent1 '#c2' \
    Agent2 '#c1 #c3 #c2' \
    Agent3 '#c3' \
    /M \
    '#c1 +o bisqwit' \
    '#c2 +mnsto bisqwit' \
    '#c3 +ooo bisqwit bisqbot Agent2' \
    '#c3,#c1 +v Mog' \
    '#c4 +o bisqwit' 

Result:

  W #c4 M +o bisqwit
  M Agent1 #c2 +omnst bisqwit
  M Agent2 #c1,#c3 +ov bisqwit Mog
  M Agent3 #c3 +ooo bisqwit bisqbot Agent1

If you just want to combine actions but don't have a list of agents to do it, specify one agent that is on all the channels.
 
For example, with this task list (file tasklist.txt):

M #Huffi +o Guffi
M #Frumble +o nngh
M #Frumble +o Zonk
M #fozz +o nngh
M #fozz +o Zonk
M #Muffi +o Guffi
M #fiuu +o nngh
M #fiuu +o Zonk
M #sc2.ja +o nngh
M #sc2.ja +o Zonk

and this shell command:

fn=tasklist.txt
chanlist="$(echo `sed 's/^..//;s/ .*//' <$fn |sort|uniq`)"
sed s/^..// <"$fn"|tr '\n' '\0'|xargs -0 modecombiner --notest _ "$chanlist" /M

You get this task list:

_ M #Huffi,#Muffi +o Guffi
_ M #Frumble,#fozz,#fiuu,#sc2.ja +oo nngh Zonk

Okay, this might not look as simple as it is, but the result is nice, isn't it?
The --notest is there to allow grouping more than three parameters for modes.
