This is the support archive of 15-780 Graduate AI homework 3.
See the problem set for a list of functions and short descriptions.
Use the support functions to access the Bayesian network data structure.
Type "help function_name" in Matlab for detailed documentation of a function,
or read the function code itself.

enumeration_ask.m and mcmc_ask.m are skeletons and APIs for you to 
fill in your implementation. Check out the hints!
If it is necessary for you to use a different API, 
please provide a file named NOTES about how to call your function. 

For those who want to use a language other than Matlab (not recommended),
you need to write support code similar to the functions here by yourself.
On creating the Bayesian networks, especially the CPT of the pedigree network,
see create_alarm_bn.m and create_pedigree_bn.m.
