NISSY(1) BSD General Commands Manual NISSY(1)

NAME

nissy — a Rubik’s cube solver and FMC assistant

SYNOPSIS

nissy
nissy command [options...] When run without any argument an interactive shell is launched, otherwise the provided command is executed and nissy terminates. The commands that can be run in the interactive shell are the same that can be run non-interactively and are provided below.

DESCRIPTION

nissy is a Rubik’s Cube solver. Its optimal solver function uses Kociemba’s one-step algorithm (huge optimal solver), and its performance is comparable to that of Kociemba’s implementation in Cube Explorer. nissy can also solve different substeps of the Thistlethwaite’s algorithm and more.

COMMANDS

The available commands are the following:

commands

List all available commands.

help [command]

Display help. If no command is given, a generic help message is printed, otherwise a specific help relative to command is returned.

print scramble

Display a text-only description of the cube obtained after applying scramble.

quit

Quit nissy.

solve step [
options] scramble

Solve the given step on the given scramble. By default it finds only one (shortest) solution, without using niss, and it displays the number of moves at the end of the line. The options for the solve command are the following:

-m min

Only look for solution that are at least min moves long.

-M MAX

Only look for solution that are at most MAX moves long.

-s n

Try to find n solutions.

-a

Print all solutions: some solutions are filtered out by default for some steps, for examples EOs that finish with F', with this options they are not.

-n

Allow use of NISS.

-o

Only find solutions that require the minimum number of moves.

-p

Plain style: do not print the number of moves.

-v

Verbose mode: print some information during the search and print each solution as it is found instead of only printing them all together at the end.

steps

List all available steps for the solve command.

version

Display version information.

ENVIRONMENT

Data is stored in the folder pointed to by $NISSYDATA. If that variable is unset the folder $XDG_DATA_HOME/nissy or $HOME/.nissy is used instead.

EXAMPLES

The command:

nissy solve -v "R'U'FD2L2FR2U2R2BD2LB2D'B2L'R'BD2BU2LU2R'U'F"

Returns:

Found 0 solutions, searching depth 0...
Found 0 solutions, searching depth 1...
(some more lines)
Found 0 solutions, searching depth 16...
D2 F' U2 D2 F' L2 D R2 D F B2 R' L2 F' U' D

The command:

nissy solve eofb -m 4 -M 5 -n -s 6 "R'U'FD2L2 FR2 U2R2BD2 L B2 D' B2 L' R'"

Returns:
