CONDITIONALLY_UNAVAILABLE

CONDITIONALLY_UNAVAILABLE是一个条件不可用的标识符，通常用于表示某个功能或方法在特定条件下不可用。这个标识符可以在代码中使用，以便在编译时或运行时根据条件来控制功能的可用性。

在软件开发中，有时候需要根据不同的环境或配置来确定某个功能是否可用。例如，某个功能可能只在特定的操作系统版本下可用，或者只在特定的硬件设备上可用。为了实现这种条件性的功能可用性，可以使用CONDITIONALLY_UNAVAILABLE标识符来标记相关的代码块或方法。

使用CONDITIONALLY_UNAVAILABLE标识符可以帮助开发人员更好地管理和控制代码的可用性，从而提高代码的灵活性和可维护性。

Use indentation to denote the code conditionally executed by this if

Certainly! Here's an example of using indentation in Python to denote the code conditionally executed by an if statement:

x = 5

if x > 0:
    print("x is positive")
    print("This statement is also executed because it's indented")
    
print("This statement is not indented, so it's always executed")

In this example, the code inside the if statement (the two print statements) is executed only if the condition x > 0 is true. The code outside the if statement (the last print statement) is always executed, regardless of the condition. The indentation is used to group the statements together that are conditionally executed.

▪ Each sensor depends only on where the ghost is ▪ That means, the two sensors are conditionally independent, given the ghost position ▪ T: Top square is red B: Bottom square is red G: Ghost is in the top ▪ Givens: P( +g ) = 0.5 P( -g ) = 0.5 P( +t | +g ) = 0.8 P( +t | -g ) = 0.4 P( +b | +g ) = 0.4 P( +b | -g ) = 0.8

每个传感器仅取决于鬼的位置。这意味着，给定鬼的位置，两个传感器是条件独立的。T: 顶部正方形是红色的 B: 底部正方形是红色的 G: 鬼在顶部。给定：P(g)=0.5，P(-g)=0.5，P(t|g)=0.8，P(t|-g)=0.4，P(b|g)=0.4，P(b|-g)=0.8。
