Editing a file based on a pattern appearance

I have a file that contains text and numbers like this: state(1, s(1,a), [s(1,b)]). state(1, s(1,b), [s(1,a)]). state(1, s(2,a), [s(2,b)]). state(1, s(2,b), [s(2,a)]). state(1, s(3,a), [s(3,b)]). state(1, s(3,b), [s(3,a)]). state(1, s(4,a), [t(1), t(2)]). state(1, s(5,a), [t(1), t(3)]). state(1, s(6,a), [s(6,b)]). state(1, s(6,b), [s(6,a)]). …so on I want the numbering with in s(x,y) to change as […]

How to count non-blank answers in a list of cells

I have averaged values across a number of non-contiguous discrete cells in a row using the average function, which conveniently ignores blank cells. These cells are computed by array formulas and so many of them contain "" (generated by an iferror). There are many intervening cells containing other kinds of unrelated data so I’m unable […]

When using experience replay in reinforcement learning, which state is used for training?

I’m slightly confused about the experience replay process. I understand why we use batch processing in reinforcement learning, and from my understanding, a batch of states are input into the neural network model. Suppose there are 2 valid moves in the action space (UP or DOWN) Suppose the batch size is 5, and the 5 […]

MIPS – Delete consecutive duplicates from input

I’m trying to convert a program written in java to mips. The program asks user to enter a string and delete consecutive duplicates. For example if the users enters “abbcddeffga”, the output would be “abcdefga”. In Java everything works fine, but in MIPS I’ve probably messed up something with the registers or something else, and […]
