哪位高人能帮小弟解决这个问题，小弟不甚感激！！！
model "Burglar 1"
- ~2 `: x- Z; Nuses "mmxprs"
declarations
ITEMS = 1..8 ! 物品标号范围
8 R- ?! \. K3 _6 q7 S- P4 IWTMAX = 102 ! 允许携带的重量最大值
7 j' g$ ?9 \0 |3 ^4 Y: s( W* |VALUE: array(ITEMS) of real ! 物品价值
WEIGHT: array(ITEMS) of real ! 物品重量
take: array(ITEMS) of mpvar ! 1 表示带走物品i，0 表示不带走物品i
end-declarations
! 物品: 1 2 3 4 5 6 7 8

非常感谢楼主的福利！

VALUE := [ 15, 100, 90, 60, 40, 15, 10, 1]
WEIGHT := [ 2, 20, 20, 30, 40, 30, 60, 10]
换成
- L! |; P1 a4 S" Y$ I7 i& ZVALUE :: [ 15, 100, 90, 60, 40, 15, 10, 1]
0 z5 X+ t2 h* T/ `5 O3 _WEIGHT :: [ 2, 20, 20, 30, 40, 30, 60, 10]
4 {3 O. X' i: C, l  V! C试试！
