I am trying to get coordinates from the neighbouring nodes using a broadcast request and store them into lists. I am able to get only one of the responses and I think this happened because of collision between the responses as the nodes have responded at the same time. I have tried to use the Backoff Behavior with random backoff on the agent of neighbouring node but it didn't solved the problem. How can I sync the mechanism to avoid the collision ? I have written an agent for each blind node (which will make the broadcast request) and the neighbouring nodes.

Following are the code snippets.

Agent on blind node:

I am trying to create a dictionary where each key is a trial identification name and the associated values are a list with a number of elements as integers i.e. {'a':[1,3,4,2,1], 'b':[34,5,3,23]}. I figured I would start with some dummy data and when I use for loops and append(), it makes changes directly to my original data. I have determined that this happens when I try to add to my dict, but don't understand why.

My dummy values and code are as follows:

I have a sample script called sample.sh which takes three inputs X,Y and Z

I have 3 arrays formed from 3 lists:

In R, I am trying to change the variables inside my linear model dynamically. I have saved a character vector of variables that I want to use in my lm as moderating variables. This works well for numeric type of variables, however, it is not a good solution for the factor type variables as R does not know they are factors with levels.

My problem is outlined below with a simple example, say I have some data here...

I have an class A with multiple List attributes.

I have a dataframe imported from csv where each 'cell' is a list of values, so the csv looks like:

time,x,y,z
2020-05-01 11:38:20.177314,"['a', 'a', 'a']","['1', '2', '3']","[8.16, 0.27, 8.16]"
2020-05-01 11:38:20.637325,"['a', 'a', 'a']","['4', '5', '6']","[18.16, 10.27, 18.16]"

Each row in df are the x,y,z values to create a seaborn heatmap. I need to do a number of manipulations to the data like getting a sum of all 'z' values in each row, and recreate the heatmap for each row. I am having trouble even getting pandas to recognize the data as lists. Rather they seem to be string objects. I have tried df['zList']=df['z'].tolist(), but am still not able to work with the data as a list.

Something like:

edit : people marking it with negative research effort. let me know in comments whats wrong with question so that I can re-frame or improve my question.

I need to validate 18 columns of a excel file in java. I have columns validations matching certain criteria combined in common methods which will return a string.I need to set the value in two separate beans.

should I store them in a string and use it twice or call the method twice. currently am calling the method twice.which is the best solution. This happens for 18 columns inside a for loop.

So I have 2D function which is sampled irregularly over a domain, and I want to calculate the volume underneath the surface. The data is organised in terms of [x,y,z], taking a simple example:
