Matrix Chain MultiplicationSuppose you has to evaluate a expression like a*b*c*d*e where a,b,c,d and E is matrices. Since matrix multiplication is associative, the order of which multiplications is performed. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.For example, let A is a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There is different strategies to compute a*b*c, namely (A*B) *c and a A * (B*C).The first one takes 15000

Give the N,m,wi,di, beg M.A very standard 01 knapsack problem. Code that uses an optimized one-dimensional array. Because for this kind of problem, only I-1 's f[v] is useful for calculating the f[v of I, so using a one-dimensional array is equivalent to overwriting the previous record before i-1.Below is my

If the grip of the tire is good enough, then the rotation speed above the maximum torque starts, so that the clutch is exactly the biggest torque after the full combination, even if it is a very quick start. If the grip of a tire is smaller than the maximum torque of the engine, the first step to maximize the grip perfor

According to the official website speex, in narrow cases, the performance of the speexvbr is equal to that of the speexcbr. As a result, the product test converts the original speex CBR into a speex VBR. But I don't know what the performance will be in the fuse. Compare speexcbr with speexvbr. I would like to share with you the following results. If there is any difference, please correct me.
PS: speexcbr uses the CBR protocol under the implied data.
