[Question] How to workaround with Anki custom scheduling not being "Per Deck" about fsrs4anki

[L-M-Sherlock]

• How do I declare deck_name if I have more than one deck at the same hierarchy? [like in Core_german or 日本語]

You can use v2.1.0 https://github.com/open-spaced-repetition/fsrs4anki/blob/v2.1.0/fsrs4anki_scheduler.js

// parameters for a deck's all sub-decks
if (deck_name.startsWith("ALL::Archive")) {
    var f_s = [1.3028,1.4602];
    var f_d = [1.011,-0.8495,-1.1868,0.0417];
    var s_w = [3.2415,-0.8428,-0.0158,1.5379,2.1647,-0.3524,0.4513,1.1748];
    // User's custom parameters for sub-decks
    requestRetention = 0.85;
    maximumInterval = 36500;
    easyBonus = 1.3;
    hardInterval = 1.2;
}

FSRS4Anki depends on Anki's custom scheduling. Maybe I should propose a feature request for that to Anki.

[L-M-Sherlock]

Yes, the main is the latest version that supports setting different parameters to different decks. You can find the guide in the comments of the scheduler.js

Here's one of mine:

<div id=deck>{{Deck}}</div><br><hr>

Sorry to revive a closed issue, but just wanted to check if I understood correctly.

Right now I have 3 specific decks I wanted to apply the optimized algorithm too.

So I did it like this:

if (document.getElementById("deck") !== null) {
    const deck_name = document.getElementById("deck").getAttribute("deck_name");
    // parameters for a specific deck
    if (deck_name == "Medicina") {
        var w = [0.2928, 0.9294, 5.1375, -0.6332, -0.6345, 0.0715, 1.3676, -0.1823, 0.7659, 1.6259, -0.571, 0.7588, 0.5924];
        // User's custom parameters for the specific deck
        requestRetention = 0.85;
        maximumInterval = 36500;
        easyBonus = 1.5;
        hardInterval = 1.2;
    // parameters for a deck's all sub-decks
    } else if (deck_name == "Geografia") {
        var w = [0.893, 1.0069, 5.2526, -0.7893, -0.7092, 0.0386, 1.2696, -0.1351, 0.6625, 1.53, -0.6509, 0.8015, 0.482];
        // User's custom parameters for sub-decks
        requestRetention = 0.85;
        maximumInterval = 36500;
        easyBonus = 1.5;
        hardInterval = 1.2;
    } else if (deck_name.startsWith("Chinese")) {
        var w = [0.9634, 0.9915, 5.1104, -0.6078, -0.6789, 0.0, 1.3312, -0.0537, 0.7292, 1.7955, -0.4129, 0.4375, 0.9259];
        // User's custom parameters for sub-decks
        requestRetention = 0.85;
        maximumInterval = 36500;
        easyBonus = 1.5;
        hardInterval = 1.2;
    }
}

is this correct? The Chinese one is the only one with sub-decks.

edit: nevermind, I confirmed it was working with the webview inspector addon.

I post the feature request in Anki's forum: https://forums.ankiweb.net/t/set-anki-custom-scheduling-per-deck-option/

[YorkZ]

Thank you so much @L-M-Sherlock.

[L-M-Sherlock]

Dae gave a solution, but I think it is too technical for average users. I will test it later.

[YorkZ]

That's a smart idea though, thank you so much @L-M-Sherlock for having to do additional implementation on this.

[L-M-Sherlock]

I implement the solution of dae on #20 . You can checkout this branch to set parameters for a specific deck.

[YorkZ]

Looks like you've merged it into main so I can use the main right? Also, how do I set different parameters to different decks?

[YorkZ]

Can the deck name be placed anywhere in the Front Template? For example, adding the prefix text "Deck: " is OK right? Also, would adding a <br> and/or <hr> after the deck name be OK as well?

[L-M-Sherlock]

Yes, just don't modify the id.

Hi, thanks for sharing this project with the community. I'm trying to implement custom schedule by deck, but I have some questions that I need to clarify.
Here is my deck for the example.

1. How do I declare deck_name if I have more than one deck at the same hierarchy? [like in Core_german or 日本語]
2. If I declare deck_name with just the root of those decks, are the siblings included?
3. script should something like these right?

if (document.getElementById('deck') !== null) {
    const deck_name = document.getElementById('deck').innerHTML;
    // parameters for a specific deck
    if (deck_name == "Core\_German") {
        var f_s = [1.0994,1.1744];
        var f_d = [1.0022,-1.0578,-1.3561,0.0045];
        var s_w = [3.1375,-0.7485,-0.01,1.4304,1.9598,-0.6523,0.3455,1.0339];

        requestRetention = 0.85;
        maximumInterval = 36500;
        easyBonus = 1.3;
        hardInterval = 1.2;
    }
if (deck_name == "日本語") {
        var f_s = [0.739,1.6203];
        var f_d = [1.368,-1.4266,-1.192,0.1733];
        var s_w = [3.0237,-0.8435,-0.0222,1.2885,1.7793,-0.7082,0.7611,0.9812];

        requestRetention = 0.85;
        maximumInterval = 36500;
        easyBonus = 1.3;
        hardInterval = 1.2;
    }
}
