Currently, there is a large number of different solvers available and the number is growing. The most important distinction between the solvers is whether they attempt to find a local or a global solution. Solvers that attempt to find a global solution (so called Global Solvers) can usually not solve very large models. As a contrast most Local Solvers can work with much larger models, and models with over 10,000 variables and constraints are not unusual. If the model has the right mathematical properties, e.g. is convex, then Local Solvers will find a global optimum. Unfortunately, the mathematical machinery for testing whether a general NLP model is convex or not has not yet been developed (and is expected to be in the class or hard problems). It is almost impossible to predict how difficult it is to solve a particular model with a particular algorithm, especially for NLP models, so GAMS cannot select the best algorithm fo

But I am newbie in Matlab and I dont know if this is ok. > options = optimset('TolFun',1.0000e-1000); This is equivalent to setting the tolerance to 0. I recommend that you NOT do that. Make it something small but positive. Regardless, it doesn't matter because ... > options = optimset('TolX',1.0000e-1000); on this line you overwrite the options structure created by the previous line with one that just has a value for the TolX option set. [The same caveat holds here too.] Call OPTIMSET like this to update the options structure: options = optimset(options, 'TolX', 1e-6); > options = optimset('MaxFunEvals',100000); Ditto on the overwrite. > options = optimset('MaxIter',100000); Ditto. > x=lsqcurvefit(@myfun,x0,t,F_measured,[],[],options); > > I try estimate the parameters with this definition

I am currently refering the following link information to get the maxPwdAge from the Properties. Active Directory user password expiration date .NET/OU Group Policy Problem with my code is that var maxPwdAge = results[0].Properties["maxPwdAge"][0]; // Getting Error here maxDays = (long)maxPwdAge / -864000000000; in this line, I am getting Error as follows The time limit for this request was exceeded or "Function evaluation function evaluation error disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation." I tried IADsLargeInteger also to get the value, but I am getting the same error for the both cases object obj = entry.Properties["maxPwdAge"];// Getting Error here ActiveDs.IADsLargeInteger largeIntADSI; largeIntADSI = (ActiveDs.IADsLargeInteger)obj; But after nearly 30 secs, I am getting 240 days, the expected result from my code.It is very problematic issue. c# c#-4.0 active-directory directoryservices directoryentry share|improve this question asked Mar 19 '14 at 9:21 rkP 63 1 Application is not responding or just hung for 30 secs in the var maxPwdAge = results[0].Properties["maxPwdAge"][0]; I couldn't find the root case for this problem. –rkP Mar 19 '14 at 9:24 Solved issue as follows ActiveDs.IADsUser native = (ActiveDs.IADsUser)entry.NativeObject; DateTime passwordExpirationDate = native.PasswordExpirationDate; TimeSpan dayLeft = passwordExpirationDate.Date.Subtract(DateTime.Today); daysLeft = dayLeft.Days; –rkP Mar 19 '14 at 9:57 add a comment| active oldest votes Know someone who can answer?
