Question

我在斗智斗勇，请帮忙！下面是问题的设置。顺便说一句，为什么当有超过8个变量时我无法查看模型细节？

我已经设置了约束来将答案限制在窗口内。为变量10提供的解决方案不在约束范围内。有什么我想念的吗？

罗兰，

我添加了源代码。初始帖子不包括因为我认为浏览器输出显示设置。提前感谢您的帮助。

set.bounds（LPIR，低级=代表（-100,10）） ##设定目标方向，最大化信息比

constMat <- matrix(0.0,nrow=41,ncol=length(delta))
rightV <-rep(NA,41)
constV <-rep(NA,41)

for (i in 1:10)
{
    inx = ((i-1)*4) 

    constMat[inx+1,i] <- 1  

    rightV[inx+1] <- (pWeight[i]*.2)-actWeight[i]
    constV[inx+1] <- "<="

    constMat[inx+2,i] <- 1  
tmp1 = (pWeight[i]*-.2)-actWeight[i]  
    rightV[inx+2] <-  tmp1
    constV[inx+2] <- ">"

    constMat[inx+3,i] <- 1  
tmp1 = (pWeight[i]*.02)
rightV[inx+3] <- tmp1
constV[inx+3] <- "<="

constMat[inx+4,i] <- 1  
tmp1 = (pWeight[i]*-.02)
    rightV[inx+4] <- tmp1
    constV[inx+4] <- ">"
} 

constMat[41,]<-rep(1,10)
rightV[41] <- 0
constV[41] <- "="

for (i in 1:10)
{
    set.column(lpIr,i,constMat[,i])
}

tDelta<- delta
tRatio <- (tDelta+IR*factor)
set.objfn(lpIr,tRatio)

## cat（rightV，＆＃34; \ n＆＃34;）

set.rhs(lpIr,rightV)
set.constr.type(lpIr,constV)  
solve(lpIr,-l)  
cat(get.objective(lpIr),"\n")
##cat(tRatio,"\n")
cat(get.variables(lpIr),"\n")   
res = get.variables(lpIr)
