First of all, dynamic planning, dynamic planning this thing and recursion, can only find local relations, if you want to all listed, it is difficult, such as Hanoi. You can say that all the other layers except the last layer are moved to 2, and then the last layer to move to 3, and finally the rest from 2 to 3, this is an intuitive relationship, but it is difficult to list out, perhaps when the number of n=3 can also be simulated under, and then larger is impossible, so, such as recursion, Dynam

problem Description Many years ago, in Teddy ' s hometown there were a man he was called " Bone Collector ". Collect varies of bones, such as dog ' s, cow ' s, also he went to the grave ... The Bone collector had a big bag with a volume of V, and along he trip of collecting there is a lot of bone s, obviously, different bone have different value and different volume, now given the all bone ' s value along his trip, Can calculate out the maximum of the total value the bone collector can get

Preface Recently, the following things are annoying: I almost had to submit a project application to the school. I originally wanted to create a multi-mode IM system. However, compared with projects that passed the review in the past, there was no innovation or research value, therefore, you need to do more work in the document. This is the case for a large number of jobs in each phase. The open source code of directui has never been improved. Prepare for the software design competition at t

One, 01 backpackThere are n items and a backpack with a capacity of V. The price of item I (i.e. volume, hereinafter) is w[i], the value is c[i]. The solution of which items are loaded into the backpack allows the sum of the costs of these items to be no more than the backpack capacity and the maximum value.This is the most basic knapsack problem, the overall poi
