  1. Started with
    \[e^{-\left(1 - x \cdot x\right)}\]
    0.1
  2. Applied simplify to get
    \[\color{red}{e^{-\left(1 - x \cdot x\right)}} \leadsto \color{blue}{\frac{e^{x \cdot x}}{e}}\]
    0.1
  3. Using strategy rm
    0.1
  4. Applied add-exp-log to get
    \[\color{red}{\frac{e^{x \cdot x}}{e}} \leadsto \color{blue}{e^{\log \left(\frac{e^{x \cdot x}}{e}\right)}}\]
    0.1
  5. Applied simplify to get
    \[e^{\color{red}{\log \left(\frac{e^{x \cdot x}}{e}\right)}} \leadsto e^{\color{blue}{{x}^2 - \log e}}\]
    0.1
  6. Removed slow pow expressions

Original test:


(lambda ((x default))
  #:name "exp neg sub"
  (exp (- (- 1 (* x x)))))
