SMALLEST PROBLEM from C. Le Goues et al., "The ManyBugs and IntroClass Benchmarks

for Automated Repair of C Programs," in IEEE Transactions on Software

    Engineering, vol. 41, no. 12, pp. 1236-1256, Dec. 1 2015.

This problem file defines the following problem: takes as input four ints, computes the smallest, and prints to the screen the smallest input.

### -main

`(-main & args)`

Runs propel-gp, giving it a map of arguments.

### error-function

`(error-function argmap data individual)`

Finds the behaviors and errors of an individual: Error is 0 if the value and the program’s selected behavior match, or 1 if they differ. The behavior is here defined as the final top item on the PRINT stack.

### instructions

Stack-specific instructions, input instructions, close, and constants

### random-int

`(random-int)`

Random integer between -100 and 100

### train-and-test-data

Inputs are 4-tuples of random integers and the outputs are the minimum value of each tuple.
