[gecode-users] About ArgumentSizeMismatch exception and linear constraint

[Christian Schulte]

The argument to the linear constraint (*.col(a)) defines the coefficients
for the variables in the second argument  (*.row(d)). They  must be of the
same size (same number of arguments), naturally. If not, an exception is
thrown. 

 

Check the reference documentation of linear, it says in which cases linear
throws which exceptions.

Subject: [gecode-users] About ArgumentSizeMismatch exception and linear
constraint

 

Hi group,
Can you kindly give some hint on the possible relationship between linear
constraint and the ArgumentSizeMismatch expection?

My program is running under Virtual C++ 2008 Express Edition, and every time
I debug it. It will give below output with an arrow pointing to my linear
constraint in the editor. My linear constraint is as below:
linear(*this,scene_actor_matrix.col(a),shooting_day_and_scene_matrix.row(d),
IRT_EQ,sum,ICL_DEF);

And the exception message:
First-chance exception at 0x76a1b727 in NewSceneAllocation.exe: Microsoft
C++ exception: Gecode::Int::ArgumentSizeMismatch at memory location
0x001cf364..
Unhandled exception at 0x76a1b727 in NewSceneAllocation.exe: Microsoft C++
exception: Gecode::Int::ArgumentSizeMismatch at memory location 0x001cf364..

I also tried initializing the matrixes with proper domain and also checked
the size of the matrix. Still got the exception.

Thanks for your reply in advance.

Regards,
Yong
