If somebody is joining ILOG user meeting in Orlando (next February
3,4,5), there is an available second bed in my room, which is located
at the renaissance hotel , the host of the meeting

I want to do a squares fitting:
minimize  Sum_i{ W( i )*[G( i )-F(  X,A(i) ) ]  ^2}
subject to C(X,i=5)=0
where X is a 12-element column vector, W(i)( weight setting), G(i)

Assume I have an optimization problem with a 12-dimensional variable
and a complicated nonlinear constraint function.
To run any optimization routine I need a feasible initialization. My
problem is how to find that initialization satisfying the constraint/

I am tailoring a somewhat complex MILP transportation model which
involves penalties for earliness and tardiness and when putting in the
penalties I have increased the computation times exponentially
depending on the penalty value).

First of all thanks in advance for taking time to look at this post.
I'm wondering if there are any cplex experts out there who can tell me
how I can update the right hand side of an IloExpr
IloModel model;

Hi, All:
I have one problem about optimzation.
In my case, 3*n unkown variables
f=[f_1x,f_1y,f_1z,f_2x,f_2y,f_2z,...f_nx,f_ny,f_nz] should be

Dear Colleagues,
At the 2009 Informs Computing Society Conference, I am organizing one or
more sessions related to work on 'Decomposition Methods for Integer
Programming'. These sessions will be included under the Integer

The behavior of elementary transcendental functions, with a real
argument (x), are well known (or should be) to every science student
and researcher.  However, this is not the case for the same functions
with a complex argument (z = x+iy; x,y real).

I'd like to create a cone defined by the cone height, a set of
bearings and the slope of the cone side at those bearings.  My problem
is the cone slopes need to be smoothed without having sharp changes in
the cone side slopes.  For example, if I have (0,45) (50,70) and (180,
