I have some simple examples of exactly that here

Cooooool! Makes me wish I had a reason to do this kind of stuff in my PhD 😃 but I’m already distracted enough as it is.

Since it seems like a safe place for crazy ideas…

1. fund with kick starter
2. incentivize the heavy lift stuff with gitcoin
3. reward other contributions with high praise

What do people think a _useful_ MVP would look like?  
How much effort would that take?  
How much $ is that worth?

The problem here is that MVP isn’t actually that useful. It’s pretty easy to make a simplex solver. It’s hard to make one with good performance which is when it’s useful.

Personally, I feel that the reliability of commercial solvers is even more valuable than the performance improvements. For example, many applications can work just fine with the performance of Clp and Cbc, but it’s problematic to deploy an actual product which crashes (infrequently).
