With Python's threads, you have to handle this kindd a feature yourself. 
For example, you can create a single object containing a boolean set to 
False by default. When one of your algorithm finishes, the boolean is 
set to True. All your algorithm should regularly test this boolean and 
exit if it is True ! Note that the boolean has to be inside another 
object because Boolean types is not mutable. Now, if you really want to 
be able to "kill" your threads, you will need another thread interface. 
For example, Qt threads allows that ... and WxPython offers you some 
functions to do exactly what I described.
