如何調試clpfd程序？

我在SICStus Prolog（clpfd）中有一個程序，我想在labeling期間看看發生了什麼。我試過trace，但它太冗長，這使得很難理解實際發生了什麼（哪些值分配給哪些變量，如何傳播約束等）。如何調試clpfd程序？

一個我的程序的簡化版本：

runTT(Goal) :- 

    PLST_1 in {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59}, 
    DLST_1 in {0, 1, 2, 3, 4}, 
    DLST_1 #= PLST_1/12, 
    % T: Bo, S: A, D: 1 
    PLST_2 in {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59}, 
    DLST_2 in {0, 1, 2, 3, 4}, 
    DLST_2 #= PLST_2/12,

    Goal = [PLST_1, PLST_2], 
    labeling([], Goal).

感謝您的任何提示！

注意：我很想刪除「域名地獄」，但據我瞭解，Prolog我不能使用一個變量（例如Domain_01）。

您可以在0..59'中使用'PLST_1並在0..4'中使用'DLST_1，而不是明確枚舉域。還可以在SICStus Prolog中查看庫謂詞'domain/3'。 – mat 2013-05-09 23:20:27

@mat：我從我的數據生成序言文件。如果我用手寫的話，我會在0..59中使用'PLST_1'，但通常它並不總是如此，因爲有些值可能被禁止。謝謝，我會看看。 – 2013-05-09 23:23:48

當使用Prolog生成或後處理文件時，可以使用有限域求解器的反射謂詞來給出一個簡潔的域表示法，例如在1..4，X＃\ = 2中嘗試'？ - X， fd_dom（X，Dom）.'，它給你'X'的'Dom'域。 – mat 2013-05-09 23:30:19

我見過有一個特設debugger，但我很抱歉，我從來沒有用過它。

除此之外，我嘗試使用Markus Triska的suggested來約束求解的可視化，但除了需要修改程序之外，很可能它是一個簡單的好奇心，而不是真正的調試工具。

SWI-Prolog調試器以相當可讀的方式顯示約束存儲（歸屬變量）。因爲標籤是在Prolog中實現的，所以我認爲應該可能的 - 帶着痛苦 - 遵循標籤處理步驟進入庫（clpfd）源。

我是唯一一個真正使用SICStus Prolog的人嗎？其他人如何不像我一樣遇到類似的問題？我覺得我正在一個荒蕪的島嶼上。：））謝謝您的回答！ – 2013-05-09 20:51:19

SICStus主要是一種商業產品。然後，客戶支持將更有效地爲其客戶提供服務。 – CapelliC 2013-05-09 21:39:29

我在學校牌照方面使用SICStus。我真的不知道我是否有某種支持。我猜這不是。 – 2013-05-09 23:25:12
