-In this page you can find download links (see above), -installation instructions and -upgrade instructions -for nissy. If instead you wish to clone the -git repository, -you can use git: -

- -

-git clone https://git.tronto.net/nissy
-

- -

-For a summary of changes and a list of older versions see below. Some versions -(for example 1.0) are not available directly, but can be obtained from -the git repository. -

Installation

- -

System requirements

- -

-A full installation of nissy requires about 3.1Gb of space, -of which 2.3Gb are occupied by the huge pruning table for fast optimal solving, -and running it requires the same amount of RAM. -One can choose to never use this function and not to install the relative -pruning table. There is an alternative (slower) -optimal solving function that uses about 500Mb of RAM. - -When generating the pruning tables automatically (see the section Tables below), -at least 5.3Gb or RAM are required. -

- -

Windows

- -

-Try downloading and executing in a terminal the file nissy.exe, -then follow the instructions in the Tables section below for -installing the pruning tables. -If nissy.exe does not work, you can try following the UNIX instructions -in WSL (Windows Subsystem for Linux) or in a similar environment. -

- -

UNIX (Linux, MacOS, *BSD...)

-Download the source archive (.tar.gz). Extract it -with your favorite archive program, for example with -

tar -xvzf nissy-VERSION.tar.gz

-Open a terminal in the directory just extracted. -If you wish, edit the Makefile to match your local configuration -(this is usually not necessary, but you may want to change the -PREFIX variable to change the installation path) and run -

make

-followed by -

make install

-Then follow the instructions below to install the pruning tables. -

- -

Tables

- -

-Once you have installed nissy, run -

- -

nissy gen

- -

-to generate all the tables that Nissy will ever need. -Running this command requires around 5.3Gb of RAM, and it can take some time -(about 40 minutes on my fairly old but decent laptop, with 8 CPU threads). -

- -

-Some unnecessary technical detail: by default this command is going to use -at most 64 threads. If you want you can choose to use more threads (if your CPU -is very powerful) or fewer threads (if you for example want to run this command -in the background while you do other stuff) with the -t option, for -example nissy gen -t 1. -

- -

-Alternatively, you can -download all the tables (1.7Gb) and -copy them into the correct folder (see manual page, ENVIRONMENT -section). On UNIX operating systems this folder is either -.nissy/tables in the user's home directory or -$XDG_DATA_HOME/nissy/tables if the XDG variable is configured. -On Windows it is the same directory as the nissy.exe executable -file. -

- -

Upgrading

-If you already have nissy installed and you want to upgrade to a more -recent version, you can simply repeat the installation process: -

-On Windows: simply replace nissy.exe with the new file with the same name. -
-On UNIX systems: download the new version of the source code, extract it in -a new folder and run make and make install again. -

-Between each version new table files might have been added, or old ones -may be not used anymore. Nissy will deal with this automatically. -

Nissy v1

- -

-Nissy v1 was released in 2020. It was slow, full of bugs and the code -was quite terrible. But in practice it got its job done most of the time. -
