Test instructionsThere are n toys, to be divided into groups, toys with the same width, but the length of C may be different . Give the order of n toys, any number of consecutive toys can become a group. The cost of the interval [i,j] becomes a group of cost= (J-i+sigma (Ck)-L) 2 and I. Given N and L and the length of each toy, what is the sum of the costs after the question is grouped? (nIdeas:Note: The cost is not a straight line function, the total

The main topic: The n number is divided into groups, and the number of each group in the original array should be continuous, each group will incur the cost of sum (i)-sum (j) +i-j-1-m,m is known constant. Minimum cost.Topic Analysis: The definition of DP (i) represents the minimum cost of grouping the first I elements, and the state transition equation is obvious:DP (i) =min (DP (j) +[sum (i)-sum (j) +i-j-1-m)]^2).

The solution to the first slope optimization question is still not very thorough.
I can recommend a blog here.

Well written, but it may not be clear in some places.
Let me explain my understanding of slope optimization:
It is an optimization that finds a dynamic planning question, TLE, and then it happens to be in line with some crazy nature.
In essence, it is limited to create
