是否可以通过预编译的二进制文件(交互式 shell)求解 QP?
我尝试了几个样本,但没有一个有效。我错过了什么吗?
Minimize
obj: a + b + [ a^2 + 4 a * b + 7 b^2 ]
Subject To
c1: a + b >= 10
End
在这个我得到以下消息:
[src/scip/reader_lp.c:147] ERROR: Syntax error in line 3 ('Subject'): expected '/2' or '/ 2' after end of quadratic part in objective.
input: Subject To
^
[src/scip/reader_lp.c:3362] ERROR: Error <-2> in function cal
另一个例子:
Maximize
obj: x1 + 2 x2 + 3 x3 + x4
Subject To
c1: - x1 * x3 + x2 + x3 + 10 x4 <= 20
c2: x1 - 3 x2 + x3 <= 30
c3: x2 - 3.5 x4 = 0
Bounds
0 <= x1 <= 40
2 <= x4 <= 3
General
x4
End
这是这里的输出味精:
[src/scip/reader_lp.c:147] ERROR: Syntax error in line 4 ('x3'): expected sign ('+' or '-') or sense ('<' or '>').
input: c1: - x1 x3 + x2 + x3 + 10 x4 <= 20
