0.75+3/4x5/11+75%x6/11 简便计算0.75+3/4x5/11+75%x6/11 简便计算急
帮我用lingo或者lindo算个题呗?x1+x4+x5+x6+x7>20x1+x2+x5+x6+x7>13x1+x2+x3+x6+x7>10x1+x2+x3+x4+x7>12x1+x2+x3+x4+x5+>16x2+x3+x4+x5+x6+>18x3+x4+x5+x6+x7>20格式不对也改下哈,>在lingo中应该和>=一样吧?min=(5x1+4x2+3x3+3x4+3x5+3x6+4x7)
数学建模的LINGO使用问题modelmin=x0+x11+x8+x9;x0+x1+x2+x3+x4+x5+x6+x7+x8+x9+x10+x11=11;x0+x1+x3+x4>=4;x1+x2+x4+x5>=4;x2+x3+x5+x6>=4;x3+x4+x6+x7>=3;x4+x5+x7+x8>=3;x5+x6+x8+x9>=4;x6+x7+x9+x10>=4;x7+x8+x10+x11>=2;x8+x9+x11+x0>=2;x9+x10+x0+x1>=1;
