We'll skip over those lines the first time we run. Since the summed up number will be stored in box 2, the top of our program can be fetching the number from box 2, and bringing it to the OUTBOX. Box 0 will be where we store the other number that we're multiplying by, and it will be the number we bump down while we count how many times we add. Box 1 will be where we cache that number so that we know how much to add each time. We'll start by assuming that three boxes are going to used for the following tasks: Box 2 will be where we hold onto the sum of the number we're adding to itself. Since this is another case where you can't complete the size challenge and the speed challenge with one single program, the solutions will be split out again.ġ5 instructions can be a tough number to hit on this challenge, but it can be done with enough proper setup. But if the zero is the first number, you still need to grab the next number off the IN conveyor or your answer will be wrong. If the second number you pick up is the zero, put it on the OUTBOX. Naturally when either number is a zero, you want to simply put a zero in the OUTBOX and move on to the next two numbers.

This is what's known as an 'edge case,' a situation that runs outside the normal circumstance that you have to write extra code to specifically handle. You don't have to worry about negative numbers, but there is another concern that you still have: multiplying by zero. Then you'll send the result to the OUTBOX. From there, you will proceed to add one of the values to itself, while you bump the other value down by one, and repeat this process until the value you're bumping down reaches zero. So to solve this problem, you will copy two values into two boxes. Multiplying m by n is the same as adding m to itself n times. Fortunately, multiplication can be performed purely with addition. But you clearly don't have a multiplication instruction. If you do, the program that you write will reflect the labels that you've designated rather than the number of the box.Īs you can tell from the instructions, you must now write a multiplication program. If you want to mark a box with a particular purpose, you can click on the box and draw your own label for it. The inclusion of step by step debugging tools to watch where your program’s holes are was really beneficial, and encouraged understanding how your solution works, rather than just being content with the success itself.Like comments, labels are purely for your own benefit.

If a data set exists for which your program would break, that data set is provided to you, so you can debug the program step by step and see where it falls apart. The game also encourages players to not just successfully process a given set of data, but behind the scenes multiple sets of data are run through your program to ensure it works for every set, not just the current set.

Learning where you could cut dead weight from a programming string felt hugely rewarding. For those who keep up with the programming challenges as they are introduced, there are also a pair of optional optimization challenges for each puzzle - such as, “have fewer than X instructions in your program,” or “completely process the data in less than Y moves.” Often it’s impossible to complete both challenges with a single program, so it pushes you to re-optimize processes rather than just finding a solution that works. Still, let’s talk a little about what Human Resource Machine gets right. It tries and fails to straddle a difficulty line. I feel like Machine doesn’t really commit fully to being a game for new coders or for experienced programmers. For those who already program, much of the early game will likely be too easy.

It’s presented in advertising as a step by step tutorial on learning programming logic, but for newcomers to code some of the logical leaps are to complex to get through any method besides trial and error. I think ultimately this is my biggest problem with Human Resource Machine. That kind of logic takes several considerable leaps, on top of trying to master a technique you only just learned for the first time. You can copy from or to limited memory spaces on the floor, add held and stored values together or increase a memory value by one. Here’s one: build a machine that recognizes zero sum strings, then add up everything in the string, then create a Fibonacci sequence up to but not exceeding the value of your zero sum string, and place all values from the resulting Fibonacci sequence into the outbox using a limited set of tools.
