Description: Construct the short length of QC LDPC codes without girth 4 and girth 6-The Program to construct the short length of QC LDPC codes without girth 4 and girth 6
Copyright (C) Yang XIAO, Jun FAN, BJTU, July 26, 2007, E-Mail: yxiao@bjtu.edu.cn.
This program presents an approach [1] for constructing the short length of LDPC codes with girth 8. First, we design 3 submatrices with different shifting functions given by our schemes, then combine them into a matrix according to our approach, finally, expand the matrix into a desired parity-check matrix using identity matrices and cyclic shift matrices of the identity matrices.
The simulation results in AWGN channels show that the codes which can be obtained by the generator matrix derived from this check matrix for encoding the random information bits are as good as random LDPC codes [1].

Description: This paper present a Template Sparse Library for Power Systems (TSLPS) developed in C++. Its aim is to provide a
coherent platform for many power system applications such as Load Flow(LF), Short Circuit(SC), Optimal Power Flow(OPF)
and Transient Stability (TS). The TSLPS is inspired by the recent template numerical library but considers only power system
characteristics, eg for a class of large sparse symmetric matrices over real and complex numbers. Template facility of C++
is used to write a generic program on float, double and complex data types. The paper describes the generic code developed
and its impact on the power system applications. LF and SC analysis have been successfully applied to the solution of several
power systems and presented good computational performance. Platform: |

Description: zoj094
Matrix multiplication problem is a typical example of dynamical programming.
Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.
For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix.
There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C).
The first one takes 15000 elementary multiplications, but the second one only 3500.
Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.
