Most of them earn millions (2) as well, in television revenues, sponsorships. They also benefit (3) from the added publicity they get via their teams. Big-name universities (4) each other in the most popular sports. Football games at Michigan regularly (5) crowds of over 90, 000. Basketball’s national collegiate championship game is a TV (6) on a par with any other sporting event in the United States, (7) perhaps the Super Bowl itself. At any given time during fall or winter one can (8) one’s TV set and see the top athletic programs--from schools like Michigan, UCLA, Duke and Stanford-- (9) in front of packed houses and national TV audiences.

The athletes themselves are (10) and provided with sch61arships. College coaches identify (11) teenagers and then go into high schools to (12) the country’s best players to attend their universities. There are strict rules about (13) coaches can recruit--no recruiting calls after 9 p. m. , only one official visit to a campus--but they are often bent and sometimes (14) . Top college football programs (15) scholarships to 20 or 30 players each year, and those student-athletes, when they arrive (16) campus, receive free housing, tuition, meals, books, etc.

In return, the players (17) the program in their sport. Football players at top colleges (18) two hours a day, four days a week from January to April. In summer, it’s back to strength and agility training four days a week until mid-August, when camp (19) and preparation for the opening of the September-to-December season begins (20) During the season, practices last two or three hours a day from Tuesday to Friday. Saturday is game day. Mondays are an officially mandated day of rest.

题型:填空题

阅读下列说明和C代码,将应填入 (n) 处的字句。

[说明]

设某一机器由n个部件组成,每一个部件都可以从m个不同的供应商处购得。供应商j供应的部件i具有重量wij和价格cij。设计一个算法,求解总价格不超过上限cc的最小重量的机器组成。

采用回溯法来求解该问题:

首先定义解空间。解空间由长度为n的向量组成,其中每个分量取值来自集合1,2,…,m),将解空间用树形结构表示。

接着从根结点开始,以深度优先的方式搜索整个解空间。从根结点开始,根结点成为活结点,同时也成为当前的扩展结点。向纵深方向考虑第一个部件从第一个供应商处购买,得到一个新结点。判断当前的机器价格(c11)是否超过上限(cc),重量(w11)是否比当前已知的解(最小重量)大,若是,应回溯至最近的一个活结点;若否,则该新结点成为活结点,同时也成为当前的扩展结点,根结点不再是扩展结点。继续向纵深方向考虑第二个部件从第一个供应商处购买,得到一个新结点。同样判断当前的机器价格(c11+c21)是否超过上限(cc),重量(w11+w21)是否比当前已知的解(最小重量)大。若是,应回溯至最近的一个活结点;若否,则该新结点成为活结点,同时也成为当前的扩展结点,原来的结点不再是扩展结点。以这种方式递归地在解空间中搜索,直到找到所要求的解或者解空间中已无活结点为止。

[C代码]

下面是该算法的C语言实现。

(1)变量说明

n:机器的部件数

m:供应商数

cc:价格上限

w[][]:二维数组,w[i][j]表示第j个供应商供应的第i个部件的重量

c[][]:二维数组,c[i]D]表示第j个供应商供应的第i个部件的价格

bestW:满足价格上限约束条件的最小机器重量

bestC:最小重量机器的价格

bestX[]:最优解,一维数组,bestX[i]表示第i个部件来自哪个供应商

cw:搜索过程中机器的重量

cp:搜索过程中机器的价格

x[]:搜索过程中产生的解,x[i]表示第i个部件来自哪个供应商

i:当前考虑的部件,从0到n-1

j:循环变量

(2)函数backtrack

int n=3;

int m=3;

int cc=4;

int w[3][3]=1,2,3,3,2,1,2,2,2;

int c[3][3]=1,2,3,3,2,1,2,2,2;

int bestW=8;

int bestC=0;

int bestX[3]=0,0,0;

int cw=0;

int cp=0;

int x[3]=0,0,0;

int backtrack (int i)

int j=0;

int found=0;

if(i>n-1) /*得到问题解*/

bestW=cw;

bestC=cp;

for(j=0; j<n; j++)

(1) ;

return 1;

if (cp<=cc)(/*有解*/

found=1;

for(j=0; (2) ; j++)

/*第i个部件从第j个供应商购买*/

(3) ;

cw=cw+w[i] [j];

cp=cp+c[i] [j];

if (cp<=cc&& (4) )/*深度搜索,扩展当前结点*/

if (backtrack(i+1)) found -1; )

/*回溯*/

cw=cw - w[i] [j];

(5) ;

return found;

(4)处应填()。
