ThatThe right part indicates that all the free x in T1 is replaced with T2.Example: (λx.x) y→y(λx.x (λx.x)) (u r) →u R (λx.x)"Because the abstract body:x (λx.x) on the left, only the first X is free. 】The term is called redex("reducible expression"), and the above rule overrides a redex, called Beta-reduction.Third, the Lambda-calculus evaluation strateg

The components of the same function are reserved only one, for example: Friends, Growingio, own statistics and other functions of repetition;
Use Redex to optimize; the experiment Redex found that the APK volume is really a little bit smaller, but the boot speed has not changed and may need to be studied.
