这段代码缺少优化目标函数的定义,应该加上“minimize”或“maximize”关键字来定义优化目标函数。同时,约束条件的末尾应该加上分号,正确的代码应该是这样的:
```
minimize min = ((x-14)^2+(y-15)^2)^1/2;
subject to:
(x-8)^2+(y-9)^2 <= 49;
x >= 2;
x <= 13;
x + y <= 24;
end;
```

这段lingo代码哪里有问题model: min = ((x-14)^2+(y-15)^2)^1/2; (x-8)^2+(y-9)^2<=49; x>=2; x<=13; x+y<=24 end;
这段Lingo代码的问题在于它的约束条件没有被正确地定义。在Lingo中,约束条件应该写在“subject to”语句后面,并且每个约束条件应该单独一行。因此,正确的代码应该是这样的:
```
model:
min = ((x-14)^2+(y-15)^2)^1/2;
subject to:
(x-8)^2+(y-9)^2<=49;
x>=2;
x<=13;
x+y<=24;
end;
```
请注意,我没有改动目标函数的代码,因为它本身并没有错误。
