Question

Byzantine Generals Problem and Solutions 

Based on the proposed solutions use any code you want to demonstrate one of the solutions.

Include documentation describing your code

include comments in your code describing each step

Answer 1

Python code screenshot

#army 1 has 10 soldiers
army1soldiers=[1,2,3,4,5,6,7,8,9,10]
#army 2 has 10 soldiers
army2soldiers=[11,12,13,14,15,16,17,18,19,20]
#numbers denotes names of each soldiers
#Assume more number of soldiers dont mean assured victory
#enemycity has 10 soldiers too; numbers as identifiers
enemycity=[21,22,23,24,25,26,27,28,29,30]
import random
random.seed(0)
#Assume messenger is sent by army 1 first
#One of the army 1 soldier is chosen as the messenger
messenger = random.choice(army1soldiers)

#messenger carries a secret flag with him to assure
#he is from the same army
#this flag information is only available to the army
#if flag with messenger is his own flag,
#messenger is real,else messenger is replaced
ourcityflag=0
enemycityflag=1
ismessenger="unknown"
noofmessengerssent=0
while ismessenger!="real" or noofmessengerssent==len(army1soldiers):

flagwithmessenger=random.choice([0,1])
if flagwithmessenger==0:

ismessenger="real"

else:

ismessenger="replaced"

noofmessengerssent = noofmessengerssent + 1

if ismessenger=="real":

print("Time to attack. We will win.")

else:

print("All the army 1 members are gone. We will lose.")

Side note

If we simulate this solution to the 2 generals problem, the probability of the army to win are very high.

But 100% guarantee to winning cannot be assured with this solution.
