1. Can I use PIFOP for free indefinitely?
Yes. In the free tier, you can always use NEOS and GLPSOL to solve your optimization models.
2. How does the free trial works?
You get full access to your chosen PIFOP plan during your free trial. There is no obligation to continue beyond the trial. Your card will be charged at the end of your trial unless you cancel before then. You can cancel via your subscription settings.
3. Do my collaborators also need paid plans?
Not necessarily. Features that apply to your projects, such as persistent execution and maximum number of files, will also benefit your collaborators. However, some features are applied in the account level, such as the ability to use Opt-servers. Account level features are not extended to your collaborators.
4. What are the supported payment methods?
Credit cards and, for annual subscriptions, bank transfer.
5. Can I change my plan later?
Yes, you can always change your plan via the subscription management page. This includes upgrading, downgrading, switching billing options and adding and removing subscription keys.
6. Should I choose monthly or annual billing?
Annual subscribers get 12 months for the price of 10. But if you are just getting started with PIFOP, you may want to try it for a few months first.
7. How do I get PIFOP for multiple people?
The Enterprise plan allows you to get discounted Subscription Keys that you can distribute to whoever you want.
8. I heard that Universities have special discounts.
