Some materials from my digital library. (I have not yet read all the materials in this library. Some of them are just for reference or future reading.)
I occasionally maintain a non-exhaustive list of some resources related to Combinatorial Reconfiguration.
My YouTube channel.
- See also a Combinatorial Reconfiguration Playlist.
See this page for some documents I translated.
See this page for all TeX resources I created/collected.
Some Chocolatey packages (see also this page) and AUR packages I am maintaining.
If you are interested in trading crypto currencies, I recommend checking out Remitano. If you register an account with Remitano, use my link or mention my introduction code 8362442. Of course, it is best to do your own research before investing.
Overleaf – An online LaTeX editor which is quite useful for research collaborations.
InfiniCLOULD – A nice cloud storage service that supports WebDAV. I mainly use this service for storing data in my Zotero library. Initially, you can have 20GB of storage space for free. If you find it useful, enter my referal code TEAYR in your InfiniCLOUD’s My Page to help me get extra 2GB bonus space for one year.
temp.sh – Upload and share files from command line.
This page contains a list of PDF copies of AFSA News Letter in Japanese.
