Using constraint programming to schedule generic experiments in an automated lab. Experiments are complex and fragile so we expose a dsl for describing the constraints and objectives of each task so that the biology/chemistry doesn't go awry. One of the hardest parts of this isn't the optimization but the upfront work of defining what is/isn't necessary to be able to encode about an experiment. You want the api to provide as much control as possible without allowing the author to over constrain the problem, or introduce irrelevant steps into an experiment just because that's how they're done by hand.

#112I am working on software that makes building web apps faster, easier and more secure.
You host a copy of my web application, and it handles all your user account stuff with modules that add organizations, Stripe Subscriptions and marketplaces powered by Stripe Connect. You write your application with its own web server in whatever language and the two servers form one site.
At the moment I am trying to finish automating my documentation based on the test suites including API details from API tests and screenshots from UI tests.
I am looking for testers if you are building a SaaS or a Connect marketplace.

#113I'm trying to figure out the appropriate discount rate and methodology that governments should use when doing cost-benefit analysis of big expenditure projects (e.g. infrastructure). It would seem that economists have been arguing about this for many decades now with no end in sight.
There are some interesting value-judgements that have to be made here (e.g. do we value the consumption of future generations more/less than present consumption?), so I suspect there will never be an objective answer to this question.

That's really cool! I just started learning about constraint programming using Z3, and scheduling is the first area I'm looking at. Do you have any advice or resources you found useful? Much of the underlying theory goes over my head, but I'm not sure how much of it I need to be productive.

#115Dental treatments, besides being very expensive, are often (up to 28%) unnecessary. This happens because no-one keeps dentists in check. I am trying to make dental treatment and diagnosis reviews easy, cheap, reliable and fast.
I suppose it won't save me, but <3 for working on this. I need work done, but I don't have dental insurance, will have to pay out of pocket, and have yet to overcome the analysis-paralysis problem of finding someone who'll charge a fair price, do good work, and won't add any more holes than I need.

#116I wrote a browser based simulation game on my spare time:

It's already got a pretty sophisticated production logic, and also a unified market.
Looking to add a few functionality like child support, new resource types and maybe eventually a governmental system. Can even try out different government strategies.
If you have any ideas please share. It's been my passion for 2020 so far.

What do infrastructure groups underwrite to? Should be a decent starting point. Theres advisory groups that do only infrastructure projects for public private partnerships. Might be a helpful start.

#118Models to detect strokes in medical images to be deployed in a hospital.
What specifically are you looking at? DWI MRI? CT Perfusion? AI models?

#119I work on things like the datasets you can find here:

Teaching machines to diagnose cancer with superhuman sensitivity and specificity makes it easy to sleep at night.

#120Data-driven robot control methods for solving furniture assembly.
It's an interesting problem, requiring both dexterous manipulation and long-term planning. It's also compositional, so I believe some form of hierarchical control and planning can solve it.
