哪位高人能帮小弟解决这个问题，小弟不甚感激！！！
model "Burglar 1"
/ Z: q2 ?% n1 C8 ~8 Nuses "mmxprs"
3 e8 D) f" k- b6 B" m* qdeclarations
ITEMS = 1..8 ! 物品标号范围
! u: @: i# |( L. G1 L; r9 tWTMAX = 102 ! 允许携带的重量最大值
VALUE: array(ITEMS) of real ! 物品价值
: O- X1 b$ U0 f5 l; C/ CWEIGHT: 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
4 b- Z7 j/ w: f- q9 eVALUE := [ 15, 100, 90, 60, 40, 15, 10, 1]
* R3 }! i* \+ O/ Z1 OWEIGHT := [ 2, 20, 20, 30, 40, 30, 60, 10]
! 目标: 使带走的总价值最大
* L6 l2 N$ y5 n  O- P; e7 x% AMaxVal:= sum(i in ITEMS) VALUE(i)*take(i)
7 f5 L# F8 g; d1 s0 v" Z! 重量限制
sum(i in ITEMS) WEIGHT(i)*take(i) <= WTMAX
! 所有变量取值都为0 或1
# C3 k. u: o6 z) Iforall(i in ITEMS) take(i) is_binary
7 M6 ^/ m" S3 N# Jmaximize(MaxVal) ! 求解混合整数问题
" t) f( w$ p" e$ O. k! 打印输出结果
9 m6 i$ L! M3 I  F0 ~5 q7 dwriteln("Solution:\n Objective: ", getobjval)
forall(i in ITEMS) writeln(" take(", i, "): ", getsol(take(i)))
end-model
这段程序运行不了

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]
" ~: r! a) a- [+ O& N换成
VALUE :: [ 15, 100, 90, 60, 40, 15, 10, 1]
WEIGHT :: [ 2, 20, 20, 30, 40, 30, 60, 10]
试试！
