By default the algorithm used is L², the possibilities are:
+ 0: L² (external crate)
+ 1: BKZ with L² oracle
+ 2: DeepLLL (not working properly)
+ 3: L² (non external crate)
### generating values ### generating values
The script gen_values can be used to generate test values The script gen_values can be used to generate test values
``` ```
python gen_values.py [--noise-bits <number of noise bits>] [--number <number of values to generate>] usage: gen_values.py [-h] [--noise-bits NOISE_BITS] [--p-bits P_BITS] [--number NUMBER]
Generate test input for AGCD computation
options:
-h, --help show this help message and exit
--noise-bits NOISE_BITS
Number of noise bits (default: 5)
--p-bits P_BITS Number of key bits (default: 16)
--number NUMBER Number of numbers to generate (default: 20)
``` ```

### test script
```
usage: script.py [-h] [--noise-bits NOISE_BITS] [--p-bits P_BITS] [--min-values MIN_VALUES] [--max-values MAX_VALUES] [--trials TRIALS]
Test AGCD with varying number of test values.
options:
-h, --help show this help message and exit
--noise-bits NOISE_BITS
Number of noise bits
--p-bits P_BITS Number of bits for p
--min-values MIN_VALUES
Minimum number of test values
--max-values MAX_VALUES
Maximum number of test values
--trials TRIALS Number of trials per setting
