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

+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 3Gb 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. +

+ +

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...)

+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. +Follow the instructions below to install the pruning tables. + +

Tables

+ + + + + + + + + +

	Zip file
Tables	nissy-tables.2.0.zip (63Kb)

+Note: the version 2.0 at the end of the file name is +only indicative. Later versionw will use the same tables, unless +otherwise specified. +

+ +

+Nissy needs certain large tables to work. These tables are by default +generated the first time they are needed (e.g the first time you ask to solve a +certain step) and then saved to a file. Whenever these tables are needed again, +nissy simply loads the corresponding file from the hard disk. +

+ +

+The very large table for optimal solving can take some time to generate +(about 1.5 hours on my fairly old but decent laptop, using 8 CPU threads). +In order to generate it you need at least 5Gb of RAM. +All other tables are much faster. +

+ +

+You can ask nissy to generate all the tables it will ever need with the gen +command. It is recommended to use more than one thread, if your CPU has them. +For example, you can run: +

+ +

nissy gen -t 8

+ +

+to generate all tables using 8 threads. You can change 8 to any number +your CPU supports, up to 64. +

+ +

+Alternatively, you can simply download all the tables 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. +

Version	Date	Comment
2.0.1	2022-02-22	Bugfix release
2.0	2021-12-29	Rewritten from scratch; much faster optimal solver

+ +

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. +
