LZ_Collection

Collection of Prototypes of LZ-Algorithms:LZW, LZ77, Approx. LZ77 (seq+ par)

Compilation

Follow these steps to compile the project:

1. Move to the top of the project directory
2. Configure CMAKE-Build:
   • (Optionally) Set LOAD_PIZZA to ON in the top CMakeLists.txt in order automatically download Testdata from Pizza&Chili Corpus
   • Execute the following command:

     cmake -S . -B build -DCMAKE_BUILD_TYPE=Release     
     

3. Compile:
   • Execute the following command:

     cmake --build build --target all
     

Usage

Example: LZ_Collection [input] [output] [algorithm] [flags..]

Argument	Description
input	Path to Input-File. For the purpose of benchmarking the option "all" will compress all files in data/ consecutively
output	Path to Output-File. File will be created if it doesn't exist yet.
algorithm	Choose from LZW, LZ77, Approx.LZ77, Approx.LZ77Par

Optional Flags	Description
-c	Compress from input to output(Default)
-d	Decompress from input to output
-b	Output Benchmark-Data into report/report.csv

Calibration

The Algorithms, especially Approx.LZ77 and Approx.LZ77Par, are dependent on Parameters and Flags. Those can be found in \include\Definition.hpp.
