Hi,
what’s wrong with creating a new array each time you need it? They are very fast to create (they will only allocate heap memory if the array is large and otherwise, creation is super-quick). I have to admit I still don’t see really what you mean by uncertain number.

The purpose i use Argument arrays to do is also just as it should to be . What i want to do is that I want to use uncertain number of Argument Arrays ,so i want to create Argument arrays dynamically. You said that they do not have a new operator by design ,so i can't use "new" way. I maybe create an certain number of Argument Arrays which is much more than i want ,and it may waste some memories. Whether there has another way to realize my thought? welcome to talk about it. Kayler. 2009/8/29 Christian Schulte <[email protected]> Hi, Argument arrays are meant for what they are called: passing arguments as is explained in detail in Section 4.2.2 in Modeling with Gecode. Using them for other purposes is a bad idea and hence they do not have a new operator by design! What you should do is use a different data structure and create and argument array just when you need it for posting a propagator or branching.

But i did it unsuccessfully. Who can give me right answer. Kayler 2009/8/29 Kayler Yao <[email protected]> hi， I want to create an object of IntArgs in my program dynamically. For instance " IntArgs *pt = new IntArgs(4); -----create an object of IntArgs with four elements" or "IntArgs *pt = new IntArgs [10];------create an array with 10 object of IntArgs." They all be compiled with errors. And i haven't seen the examples of create object dynamically in Gecode. And I want to know whether the Gecode support to create object of Gecode class ? And how ? Look forward to your reply! Kayler
