众所周知,求解一类问题,必须具备一定的条件:1、首先要有求解问题的方法。这个方法称为算法(algorithm)。例如求解线性方程组的消去法。2、其次是占用一定的设备,如利用计算机求解问题,可用占用的存贮单元来度量,存贮量可以以字(Word)为单位,占用存贮单元的数量称为问题(Problem)所需空间,亦称问题的规模(Size)。3、要花费一定的时间。例如要做一个加法79+25,依加法规则是:①运算从个位开始,相加的两个数的对应位(K)相加,所得的数的个位做为和对应位(K)的数值。所得数的十位
As we all know, to solve a class of problems, we must have certain conditions: First, we must first solve the problem. This method is called algorithm. For example, to solve the elimination of linear equations. 2, followed by the occupation of certain equipment, such as the use of computers to solve the problem can be used to measure the storage unit, storage capacity can be Word (Word) as the unit, the number of occupied storage unit called Problem Space, also known as the size of the problem (Size). 3, to spend some time. For example, to be an addition of 79 +25, according to the addition rule is: ① operation from the beginning of a unit, the sum of the two corresponding to the number of bits (K), the resulting number of bits as and corresponding bit (K) The value of. The number of ten
