A classic example of the greedy algorithm is the coin change problem. Suppose you need to give change for a certain amount of money using the fewest possible coins. The greedy algorithm for this problem is to always choose the largest possible coin denomination that is less than or equal to ...
Billy investigates the question of applying greedy algorithm to different spheres of life. At the moment he is studying the application of greedy algorithm to the problem about change. There is an amount of n coins of different face values, and the coins of each value are not limited in numb...
when none of those variables have been initialized. MATLAB is analyzing and saying that the only way that could happen and it be valid is if you happen to have functions with those names.You

The Coin Change Problem: Consider a cashier tasked with giving change to a customer. The cashier has denominations of 25 cents (quarters), 10 cents (dimes), 5 cents (nickels), and 1 cent (pennies). The goal is to provide the least number of coins that sum up to a given amount....
Problem: You have to make a change of an amount using the smallest possible number of coins. Amount: $18 Available coins are $5 coin $2 coin $1 coin There is no limit to the number of each coin you can use. Solution: Create an emptysolution-set = { }. Available coins are{5, 2...
This problem is a classic minimum coin change problem. The objective of this problem is to find the minimum number of bills we use to make a specified amount of money, given that we have unlimited amounts of 1, 5, 10, 20, 100 bills. ...
The coin of the highest value, less than the remaining change owed, is the local optimum. (Note that in general the change-making problem requires dynamic programming or integer programming to find an optimal solution; However, most currency systems, including the Euro and US Dollar, are ...
