This repository is for testing how well an A.L.I.C.E.-sized brain performs on the various implementations of RiveScript. The goal is to have a benchmark result set showing how slow the implementations are at handling a brain of this size, which can also be used to compare improvements that make Alice run better in RiveScript.

Contributions are welcome. If one of these benchmark scripts turns out not to be doing a very good job of benchmarking, send a pull request that fixes it.

This repository will also be used to discuss ideas to improve the performance of RiveScript. See the Issues for that.

You'll need to install the various RiveScript modules for each language before running their scripts:

• Go: go get github.com/aichaos/rivescript-go
• JavaScript: npm install (installs RiveScript and other dependencies)
• Perl: cpanm RiveScript
• Python: pip install rivescript

• Results-20160310 -- initial testing done on March 10 2016.

There are some weird quirks with A.L.I.C.E.

The RiveScript files were downloaded from here where they were originally converted on Feb 13 2013. A handful of triggers had empty responses (just a - symbol with no data).

An interesting quirk was that the "hello" trigger would redirect to "hi" about 50% of the time, but there is no trigger that matches "hi". This would cause certain implementations of RiveScript to run away and get a deep recursion error (in particular the JavaScript implementation). The recursive chain ends up on the push random trigger (push * in stack.rive).

Some replies end up redirecting to "random pickup line", but there is no trigger for this. It ends up matching the * trigger, which goes back to "random pickup line" sometimes and rinse & repeat. So I removed all references to "random pickup line" from the code.

The message "Hello Alice" kicks off a series of different redirects and it makes this reply take the longest. First it has to scan all through the sorted replies until it reaches hello *, which redirects to hello + redirects to Alice. There is no trigger of simply "Alice", so it ends up reaching the * trigger which redirects to random pickup line in addition to redirecting to push *.

At some point in the future I'll probably put the RiveScript fork of A.L.I.C.E. on GitHub and begin cleaning up its strange quirks. As it currently stands, it poses a real risk of bringing your chatbot down if the wrong chain of triggers gets activated.

The Alice reply set here is based on the Free A.L.I.C.E. AIML Set, converted to RiveScript using the aiml2rs script.
