Demos & Playground
Try QUBO++ in your browser, with no installation. Each demo opens in a new tab and has its own page that you can bookmark or share.
Note: These demos run on AWS Lambda with limited resources. Performance is typically several times slower than a standard PC. On a modern desktop, QUBO++ runs significantly faster.
Playgrounds
Write and run your own QUBO++ programs.
C++ Playground Write, compile and run QUBO++ programs in C++, with templates to start from.
