What Are the Ideas Behind Variations of the Coin Change Problem?


Problem: given a set of n coins of unique face values, and a value change, find number of ways of making change for change.

Assuming we can use a denomination more than once, here’s the pseudocode I came up with

1. NUM-WAYS(denom[], n, change) 2.   dp = [change + 1][n + 1] 3.   for i = 0 to n 4      dp[i][0] = 1 5.   xs = denom.sorted  6.   for i = 1 to change 7.     for j = 1 to n 8.       if xs[j - 1] > i 9.         dp[i][j] = dp[i][j - 1] 10.      else 11.        dp[i - xs[j - 1]][j] + dp[i][j - 1]  12.  return dp[change][n] 

The above algorithm is clear to me. However, if we are only allowed to use a denomination once, then line 11 changes to dp[i - xs[j - 1]][j - 1] + dp[i][j - 1], as if we are not allowed to use the current denomination at all. I’m failing to wrap my head around this. Can you explain this?

Here’re some test runs:

Change: 3, denominations: [8, 3, 1, 2] 11111 01111 01222 01233  // use once Change: 3, denominations: [8, 3, 1, 2] 11111 01111 00111 00122  Change: 4, denominations: [3, 1, 2] 1111 0111 0122 0123 0134  // use once Change: 4, denominations: [3, 1, 2] 1111 0111 0011 0012 0001 

What is the expected value from these two different coin tossing games?

Consider these two games:

Game 1: Toss 4 coins. If coins 1 and 2 are heads, you win $ $ $ 5. If coins 3 and 4 are heads, you win an additional $ $ $ 5.

Game 2: Toss 3 coins. If coins 1 and 2 are heads, you win $ $ $ 5. If coins 2 and 3 are heads, you win an additional $ $ $ 5.

My question is, which game will have the highest expected value for winnings? The case of game 1 is simple. Receiving $ $ $ 5 from tossing coins 1 and 2 and receiving $ $ $ 5 from tossing coins 3 and 4 are independent events. Therefore, if the coins lands heads with probability $ p$ , the expected value of the winnings is$ $ E(Game \; 1) = 5 p^2 + 5 p^2 = 10p^2. $ $ In game 2, we still have the probability $ p^2$ of winning the first $ $ $ 5. However, the probability of receiving the additional $ $ $ 5 from coin 3 is dependent upon having a heads in coin 2. I figured so far that $ $ E(Game\;2) = 5p^2 + x$ $ I am not sure what $ x$ is. Which result links the expected value of an event when conditional probabilities are involved?

THESES:
– Do not use js. Be sure that there is no Google Analytics, fingerprinting tools, xss. Use our site in a mode without js!
– Do not use the withdraw by transferring private keys from pre-prepared addresses with the same amounts – it is easily to track and if your session is compromised, you may lose your funds!
– Do not use coupons! Using the coupon you are linking all your addresses, otherwise no one can find it out!
– Do not use sessions!
– We do not show the mixing status either on the basis of sessions or on the basis of any other indentifiers. If these data will compromised, your translation will be de-anonymized!
– Generating a Letter of Guarantee requires location a private key from the wallet that creates the signature on the server of mixer. In case the mixer is compromised, its customers will be able to give out fake addresses and fake warranty letters. We sign the addresses that we give to clients on computers that are not connected to the Internet, then we unload the signatures together with the wallets
at our server. This ensures that addresses given to customers can in no way be compromised by a third party (intelligence agency or hackers), under the term that the client will verify the signature.
– Use every time random commission (within the tariff), charged for the services of our system. This makes it difficult to link incoming and
outcoming transactions
– Use every time randomly commission, charge miner over the entire transaction in a block. This makes it difficult to link incoming and
outcoming transactions
– Use TOR for push transactions in the blockchain network. This does not allow you to track the source that generates the transactions and link them together by IP
– Do not use external services to check the balance of incoming addresses!!!

RECOMMENDATIONS:
– Do not use 1:1 transactions! It negates all your mixing efforts
– Do not use fast transactions! The greater is the delay between incoming and outcoming transactions, the greater is the privacy
– Do not use previously used addresses as a receiving addresses! It weaks the privacy of translation
– Always use TOR!

Is it possible to create an application on a block chain without a native coin

Hello guys I’ve been pondering on some idea of creating a forex broker which will work on a block chain but i have some worries which I’m confused about…

  1. How can transactions go on in my broker if there is no coin to carry out mining activities what will the miners or validators earn as a reward of their services..

  2. Is it possible to use the blockchain only as a service of storage of information .. however this still brings us back to the first question what then will be the criteria to validate the information before storing in the blockchain…

  3. Is it possible to do run a block chain service in line with a fiat trading platform??
