Packing

Overview

The EvalPacking module evaluates organisms based off their ability to correctly “pack” bricks of bits. A brick is sequence of exactly n ones. It is packed on both sides  by  at least k zeros. The fitness is awarded to the organism based on how many bricks are correctly packed, no partial credit is given. No packing is needed in front of the first brick. See Example for more details.

Traits

For a description of each type of trait, see traits documentation that doesn’t exist yet.

Type of Trait	Trait Name	Trait Description
Private	N/A
Owned	fitness_trait	Stores the score (number of correctly packed bricks) of each organism.
Generated	N/A
Shared	N/A
Required	bits_trait	Stores the bit sequence to be evaluated.
Optional	N/A

Parameters

• size_t brick_size the number of ones necessary to make a full brick. The default is set at 6.

• size_t packing_size the minimum number of zeros necessary to pack each brick. Packing may be shared between two bricks. The default is set at 3.

I/O

Input

None.

Output

A single score based on the number of correctly packed bricks.

Example

Compiling and Running

To run MABE with the Packing Evaluator, navigate to the build directory and use the command make followed by the command ./MABE -f settings/Packing.mabe. Parameters may be set in the Packing.mabe file. To see complete output navigate to the output.csv file.
