Database testing conducted on 1000 samples: https://github.com/lambda-feedback/compareExpressions/actions/runs/25685183796/job/75406915338

13 errors out of 1000.

1. E^{x log x} ( log x + 1) could not be parsed as a valid mathematical expression. Ensure that the correct codes for input symbols are used, that the correct notation is used, that the expression is unambiguous and that all parentheses are closed.

• Issue with parsing ln exists in Python 3.8

2. Grade Mistmatch eval reports True, DB is false - Answer: 1/(1+GpGc)*D+GpGc/(1+GpGc)*R -- Response: (GcGpR+D)/(1+GcGp)

• These are equal, so the data is incorrect, and the evaluation function fixes an old issue

3. Schema validation: None should not be valid under {'type': 'null'}

• response is null

4. 2x \ cos(x^{2}) could not be parsed as a valid mathematical expression. Ensure that the correct codes for input symbols are used, that the correct notation is used, that the expression is unambiguous and that all parentheses are closed.

• Answer is written in LaTeX when it should be written in Sympy

5. -Grade Mistmatch eval reports True, DB is false - Answer: c_1*x**(m_1) + c_2*x**(m_1)*ln(x) -- Response (c_1+ log(x) c_1)x^(m_1)

• These are equal (input symbols define c_1 with the alias c_2 and visa-versa for c_2

6. 0.5waa could not be parsed as a valid mathematical expression. Ensure that correct codes for input symbols are used, correct notation is used, that the expression is unambiguous and that all parentheses are closed.

• Cannot replicate, 0.5waa parses correctly

7. 2x \ cos(x^{2}) could not be parsed as a valid mathematical expression. Ensure that correct codes for input symbols are used, correct notation is used, that the expression is unambiguous and that all parentheses are closed.

• Same as 4

8. Grade mismatch -- eval func True, db False -- Answer: -2 muA -- Response -2 μA

• We added support for unicode greek letters

9. Grade mismatch -- eval func True, db False -- Answer: 2(cos(pi/2)+isin(pi/2)) -- Response: 2( cos(π/2) + sin(π/2)*i)

• Same as 8

10. Grade mismatch -- eval func False, db True -- Answer: c_1*x**(m_1) + c_2*x**(m_1)*ln(x) -- Response: (c_2+c_2* log(x))x^m_1

• These are not equal (even with the same input symbols as 5.) DB data marked correct is from an old bug

11. \frac{1}{x \ log a} could not be parsed as a valid mathematical expression. Ensure that correct codes for input symbols are used, correct notation is used, that the expression is unambiguous and that all parentheses are closed.

• LaTeX used for answer instead of Sympy

12. Grade mismatch -- eval func False, db True -- Answer: 6(cos(5pi/6)+Isin(5pi/6)) -- Response: 6( cos(5π/6)+I sin(5π/6))

• Same as 8

13. Grade mismatch -- eval func False, db True -- Answer: mu+nu-lambda=0 -- Response: ν-λ+μ=0

• Same as 8
