knapsack problem


ematics> Given a ef="module.php?name=Lexikon&file=search&eid=1&query=set">set of items, each with a cost and a value, determine the number of each item to include in a collection so that the total cost is less than some given cost and the total value is as large as possible. The 0/1 knapsack problem restricts the number of each items to zero or one. Such ef="module.php?name=Lexikon&file=search&eid=1&query=constraint satisfaction">constraint satisfaction problems are often solved using ef="module.php?name=Lexikon&file=search&eid=1&query=dynamic programming">dynamic programming. The general knapsack problem is ef="module.php?name=Lexikon&file=search&eid=1&query=NP-hard">NP-hard, and this has led to attempts to use it as the basis for ef="module.php?name=Lexikon&file=search&eid=1&query=public-key encryption">public-key encryption systems. Several such attempts failed because the knapsack problems they produced were in fact solvable by ef="module.php?name=Lexikon&file=search&eid=1&query=polynomial-time algorithms">polynomial-time algorithms. [Are there any trusted knapsack-based public-key cryptosystems?]. (1995-04-10)
