Are there any key exchange algorithms with high failure rates (i.e. Alice and Bob often have to try multiple times to establish a common key)?

I am wondering if there are any key exchange algorithms which have a very high failure rate in the sense that there is in the neighborhood of a 50 percent change or so of establishing a common key per attempt.

Suppose that $f,g,L,M$ are functions such that $0

  1. Alice selects $a$ and sends $r=f(a)$ to Bob.

  2. Bob selects $b$ and sends $s=g(b)$ to Alice.

  3. Alice’s key is $K_{A}=L(a,s)$.

  4. Bob’s key is $K_{B}=M(b,r)$.

Ideally, one would always have $K_{A}=K_{B}$, but are there any key exchange algorithms where for mathematical reasons, $K_{A}=K_{B}$ about 50 percent of the time? Are there any reasons why such a key exchange would not be useful? It would seem that it is much easier to construct a key exchange algorithm if one could compromise on the probability that Alice and Bob will arrive at a common key.

Alice’s Caterpillar measuring the quantum state of her entangled particle collapses her connection to Bob? [on hold]

I understand that eventually in this discussion there will be some unexplained universal law that we will all have to accept as a God’s law and build every physics proof upon that. But I want to know if these 2 things written in bold are the ‘built on God’s law and explainable’ ones or are they themselves the God’s laws.

Can quantum entangled particles transfer information without any loss of time. Therefore making their ‘entangling ether connection’ faster than c. Now don’t start with the measuring will break down the entangled quantum state stuff because my second question is about the measurement/observation. From all resources regarding the quantum entanglement that I looked into, they all start with Alice measuring her particle’s state and so on .. BUT what the heck does this “Alice’s measurement” mean, I mean there could be a caterpillar inside Alice’s box of particle, and maybe the caterpillar measured it first, it’s such a dumb way to explain the collapse. Isn’t it like the classical mechanics relative velocity thingy, where frame of reference decides if the particle is still entangled for that particular observer. And so unlike the awesome pn junction tunneling that enables awesome tiny transistors, is “entanglement” just like “relative velocity” and a mere concept that can’t be used to make brand new quantum routers for high speed communication?
Also lets not pretend to be able to perceive higher dimension/solution of a gazzilion degree multivariate quantum equation to explain entanglement. Cheers!

Alice and Bob make all numbers to zero game

Alice and Bob are playing a number game in which they write $N$ positive integers. Then the players take turns, Alice took first turn.

In a turn :

  • A player selects one of the integers, divides it by $2, 3, 4, 5$ or $6$, and then takes the floor to make it an integer again.
  • If the integer becomes 0, it is erased from the board.
  • The player who makes the last move wins.

Assuming both play optimally, we need to predict who wins the game.

Example : Let N=2 and numbers are [3,4] then alice is going to win this one.

Explanation :

Alice can win by selecting 4 and then dividing it by 2. The integers on the board are now [3,2].
Bob can make any choice, but Alice will always win.

  • Bob can divide 2 by 3, 4, 5 or 6, making it 0 and removing it. Now only one integer remains on the board, 3, and Alice can just divide it by 6 to finish, and win, the game.
  • Bob can divide 3 by 4, 5 or 6, making it 0 and removing it. Now only one integer remains on the board, 2, and Alice can just divide it by 6 to finish, and win, the game.
  • Bob can divide 2 by 2. Now the integers are [1,3]. Alice can respond by dividing 3 by 3. The integers are now [1,1]. Now Bob has no choice but to divide 1 by 2, 3, 4, 5 or 6 and remove it (because it becomes 0). Alice can respond by dividing the remaining 1 by 2 to finish, and win, the game.
  • Bob can divide 3 by 2 or 3. Now the integers are [1,2]. Alice can respond by dividing 2 by 2. The integers are now [1,1]. This leads to a situation as in the previous case and Alice wins.

Problems About Logic: Alice, Bob, and Charlie, who is the one that telling lie?

I have problem to solve,

Three people have their own statement:

Alice : If Bob tells lie, then Charlie tells lie too

Bob : If Charlie tells lie, then Alice tells lie too

Charlie : If Alice tells lie, then Bob tells lie too,

Who is the lier?

I tried to figure it out by assuming three condition: Alice is telling truth, Bob is telling truth, and Charlie is telling truth, and i used truth table too and assume for false-truth combination, but i still cant solve this problem or find who is the lier. So, who is the lier?
