摘要

空间优化是一个特殊的现象,一直困扰着全世界的计算机程序员。越来越多的数据需要存储到不断减少的空间中。使用了几种技术来解压缩文件或更好地管理内存。第一个方面涉及转换背后的数学,第二个方面涉及在更小的芯片上存储更多数据的物理。提出的公式即矩阵折叠算法服务于空间优化的第一个方面,它利用数学计算来减少矩阵的大小。矩阵折叠算法是一种将方阵占用的空间减少到原始大小的25%的技术。该算法基于应用于原始值的数学计算,以便首先从右到左,然后从下到上对矩阵进行双重折叠。像许多其他算法一样,这个算法也有限制,即只有当我们考虑一个整数占用2字节空间的系统时,原始矩阵的数字应该在0到15之间。只有当我们考虑一个整数占用4字节空间的系统时,矩阵应该有从0到255的数字。

Compression using Matrix Folding Algorithm
Space optimization is a particular phenomenon which has puzzled the computer programmers worldwide. More and more data needs to be stored into ever decreasing space. Several techniques are utilized to either decompress the files or better manage the memory. The first aspect involves the mathematics behind the conversion and the second aspect involves physics to store more data on to smaller chips. The proposed formulation i.e. The Matrix Folding Algorithm serves the first aspect of Space optimization by making use of mathematical calculations to reduce the size of a matrix. Matrix Folding Algorithm is a technique to reduce the space occupied by a square matrix to a level of 25% of the original size. The algorithm is based on mathematical calculations applied on the original values in order to double fold the matrix first from right to left and then from bottom to top. Like many other algorithms this one also has limitations that the original matrix should have numbers ranging from 0 through 15 only when we consider a system where the integer takes 2 bytes of space. And the matrix should have numbers ranging from 0 through 255 only when we consider a system where the integer takes 4 bytes of space.
