[gecode-users] Fwd: Fwd: Initialize IntVArArgs from variable array a

[Christian Schulte]

I can't help you here, you must help yourself by reading MPG and
understanding the difference between integers and integer variables.

Hi !

Thank YOU for your help , i konw what i did is wrong because there is a
defference between the tow type of varibles, but how can i put my variables
that exist in vector<int> into IntVar Args or any other type of variables
used in linear constraints. It is easy to fillful the IntVarArgs by a simple
declaration like what is described in MPG , but my problem is when i have
another sort of varibles for exemple the keybord or an xml file or something
like that.

 

i tryed a simple exemple like this :

 

IntArgs R(n,20,10,15,5,25,30); // that works verry well

 

but when i have this variables (20,10,15,5,25,30) in a vector , i have to
put theme in a type that can be used in linear constraint right and this is
the problem : how can i put theme in an IntVarArgs for exemple 

 

Sorry to bother you with this stupid things but it really bother me, any
help , tahnk you 

 

PETER

How on earth should that work: you use a vector of integers (that is,
vector<int>) to initialize an array of integer VARIABLES that is,
(IntVarArgs).

 

You really need to read MPG more carefully. Maybe you meant IntArgs as an
array of integers?

Hi 

 

Sorry to be so bothring but this instruction that YOU gave me : IntVarArgs
x(v); doesn't work for me!!!!

 

let me explain: by just writing this instruction in the model it gave me
also an error because none of the declaration that exist in the site of
Gecode does match the argument list????

 

this is what i wrote : vector<int> W;

for (int i=0;i< 10;i++)

W.push_back(i);

             IntVarArgs R(W);

 

i konw there is a mistack here but i don't konw what is it ??? I'm really
new with Gecode that's why i do so my errors 

So sorry to be so bothring 

 

Thank YOU for any help at all

Hi,

I think you need to brush up on your C++, that's the type signature, not the
code you should write.  Just check our documentation, you can construct an
IntVarArgs from a vector v like this IntVarArgs x(v);

Cheers,
Guido
