Question

I have to built dynamically equations like following:

x + x/3 + (x/3)/4 + (x/3/4)/2 = 50

Now I would like to evaluate this equation and get x. The equation is built dynamically. x is the leaf node in a taxonomy, the other 3 nodes are the super concepts. The divisor represents the number of children of the child nodes.

Is there a library that allows to build such equations dynamically and resolve x?

Thanks, Chris

Answer 1

Are your equations always of this form (linear in x)?
If so, when building the equation, just set x to 1 and evaluate the lhs.
This will give you lhs = 1 + 1/3 + (1/3)/4 + (1/3/4)/2 = 1.4583..
Then calculate x = rhs / lhs = 50 / 1.4583
