# Introduction
`libpdb` provides means for creating Pattern Databases in different permutation
state spaces. In particular, it assumes that either full or partial states are
represented with a vector of integers which are all different. Eligible domains
are the N-Pancake, the sliding-tile puzzle or the TopSpin.
It supports both *MAX* and *ADD* pattern databases.
# Dependencies
Tests have been created using the [Google Test
Framework](https://github.com/google/googletest) which is necessary for both
compiling and runing the tests, see below.designed using
# Build #
To download the code type the following:
``` sh
$ git clone https://github.com/clinaresl/libpdb.git
```
To compile the source code, create first the `Makefile` with:
``` sh
$ cmake . -DCMAKE_BUILD_TYPE=Release
$ make
```
from the `libpdb/` directory created after the clone. It will build the library,
and a generator for every domain defined under `domains/`, and all the unit
tests.
It is also possible to compile separately different parts of the whole bundle.
To compile only the library do:
``` sh
$ make libpdb
```
which generates the shared library `src/libpdb.so`
To generate an executable to solve instances in a specific domain use `make
domain` where *domain* can be any of the following: `npancake` or `npuzzle`.
# Install #
To install the library in your filesystem, e.g., under `/usr/local`:
``` sh
$ cmake . -DCMAKE_INSTALL_PREFIX=/usr/local
```
Next, build it with:
``` sh
$ cmake --build .
```
and finally install the files in your filesystem (presumably with *sudo* if the
target directory requires root access):
``` sh
$ cmake --install .
```
# Tests #
This library comes with a number of unit tests that have been implemented with
[Google Test](https://github.com/google/googletest). If Google Test is available
in your computer, then you can compile and run the tests with:
``` sh
$ make gtest
$ tests/gtest
```
from the `libpdb/` directory created after the clone.
