Currently, the SetTextListSize, SetWordListSize and SetCharListSize are only for a Text configuration, not a Math configuration.
In your case, what has to be kept in mind is that our solution will return with what it considers as the closest result. In the below image, in my opinion, the "5" at the denominator resembles more to a "s" than a "5", which is why our Math recognizer returns with "s".
There is actually one rule to remember which is "the more you constrain, the better the recognition is likely to be".
Once compiled, you can add it into the assets of you project and to the math.conf, e.g. Name: standard Type: Math Configuration-Script: AddResource math/math-ak.res AddResource math/myCustomGrammar.res
This way, recognition of the above is likely to be better, but keep in mind that a mis-written character is not likely to be well recognized.

Dear 贵宾 李 ,
Thank you for your question.
Currently, the SetTextListSize, SetWordListSize and SetCharListSize are only for a Text configuration, not a Math configuration.
In your case, what has to be kept in mind is that our solution will return with what it considers as the closest result. In the below image, in my opinion, the "5" at the denominator resembles more to a "s" than a "5", which is why our Math recognizer returns with "s".
There is actually one rule to remember which is "the more you constrain, the better the recognition is likely to be".
First, I would recommend you create your own custom grammar, in which you would only keep the characters you expect (e.g. remove the letters and keep the digits). You can refer to the following part of the documentation: https://developer.myscript.com/docs/interactive-ink/1.3/android/advanced/build-custom-resources/#math
, and then compile it: https://developer.myscript.com/support/recognition-assets. You can also fine-tune it to only keep the expressions you expect (e.g. fractions, additions...)
Once compiled, you can add it into the assets of you project and to the math.conf, e.g.
Name: standard
Type: Math
Configuration-Script:
AddResource math/math-ak.res
AddResource math/myCustomGrammar.res
This way, recognition of the above is likely to be better, but keep in mind that a mis-written character is not likely to be well recognized.

感谢您的回答。语法资源文件我们已经编写了，但是不能很好的解决我们的问题，我们目前是针对中国的初中学生提供的初中数学产品，需要学生在安卓端输入初中会用到的数学符号。有较多的样式相似，但含义完全不同的答案需要录入S和5只是举个例子。数学公式提供候选项对我们来说非常有必要，请问你们是否有计划支持数学公式的候选项，如果有的话，大概什么时间可以提供给安卓版本SDK使用。以下是我们编写的语法资源文件。
