我正在尝试在OPL中编写一个脚本,该脚本将采用1和0的nxm矩阵,并为每个n返回对应的m,其中值是1。
比方说,我已经这样定义了我的数据:
col = {"r1","r2","r3"};
row = {"s1","s2"};
value = [ [1 0 1]
[1 0 0]];
我的代码现在看起来像这样:
{string} row = ...;
{string} col = ...;
float value[row][col] = ...;
{string} t = {};
tuple P {
string id;
{string} list;
{P} myPs;
execute {
for (var i in row) {
t.clear();
var id = i;
for (var j in col) {
if (value [i][j] == 1)
{t.add(j);}
}
myPs.add(id, t);;
}
writeln(myPs);
}
我试图得到的结果是:
{ <"s1" {"r1" "r3"}>
<"s2" {"r1"}>}
现在,myPS的结果是:
{ <"s1" {"r1"}>
<"s2" {"r1"}>}
答案 0 :(得分:1)
对于我宁愿编写的模型
{string} row = ...;
{string} col = ...;
float value[row][col] = ...;
tuple P {
string id;
{string} list;
}
{string} listPerId[id in row]={j | j in col: value[id][j] == 1};
{P} myPs={<id,listPerId[id]> | id in row};
execute {
writeln(myPs);
}
给出
{<"s1" {"r1" "r3"}> <"s2" {"r1"}>}
