Auto-Calculate Productivity for Selected Recipes

Post by 2833680766 »

For auto change recipe, we are always looking at avoid loosing productivity.
Now I create a machine to auto calculate productivity. Automatically calculates productivity for specific recipes by monitoring item quantity changes inside the machine.

When the recipe completion signal F is output:

If the item count decreases, it indicates normal operation. This quantity is recorded as A.

If the item count increases (all items increase), it indicates a productivity bonus. This quantity is recorded as B.

By reading the item changes on the inserter, I eliminated the impact of the inserter's picking action on the contents.
But I can't remove the effect of fluid input/output on the contents, since I can't read the pump's contents or flow rate. Specifically, even when I disable the pump, the fluid already inside it keeps flowing out, which is really frustrating.

Obviously, it can not use for Metallic asteroid crushing.

I start recording from the frame where A = 1, and continue until the frame just before A = 101. In this way, the machine runs exactly 100 cycles, and the value of B is the productivity. After that, we apply the Euclidean algorithm to A and B to obtain the minimum guaranteed productivity number.

To be honest, I’m not a fan of “guaranteed productivity,” because I feel that no matter what the productivity is, can’t I just request 100 times the raw materials at once?

The language I use is zh-CN. When I have free time, I will upload an English version.

The core implementation of the Euclidean algorithm is two arithmetic combinators: one does A % B and outputs A, the other does B % A and outputs B.

I am curious because it look smaller (better) than my version : viewtopic.php?t=113159, but on the blueprint, i can not see the same as in the picture.

Also the blueprint look like it could be made even smaller if you used pulse mode for the inserters :

Maybe there are some reason i don't understand why you use "Hold" and not "Pulse" ? it look like the purpose of some combinators is to create a 1 tick signal,but if you change the mode of the inserter, it can create 1 tick signal too, without extra combinators with *-1 but i can not read zh-CN, so it is a bit like magic, maybe it is already explained :(

Maybe you can use trains for fluid ? or a tank ? you cannot read pump flow easily, but you can read content of tanks or fluid wagon, if you read the quantity at when the receipe is finished.
Check out my latest mod ! It's noisy !
