Flatland 3
I have given the agent a sequence of move action, but it never appear on the map
Almost 3 years agoIt seems that the probelem comes from flatland.
After I update the version of flatland from 3.0.2 to 3.0.5, this strange phenomenon didnβt happen during many times of testing.
Anyway, thank you.

Almost 3 years agoI am not sure whether you can receive the notice of reply.
So I want to @you here Mr. @nimishsantosh
I have given the agent a sequence of move action, but it never appear on the map
Almost 3 years agoThanks for you answering.
But I have checked the states of agents and found that when I give it move action its state is READY_TO_DEPART.
Here is picture showing an example of the problem I meet.
I print the triple of [position, state, action] of every agent at every step.
From the purple frame, we know that the initial_position of agent[4] is [21,8].
The red frame is the triples of agent[4].
The blue frame shows the first time I give it a MOVE_FORWARD(2) action and at this step its state is READY_TO_DEPART(1).
And the yellow frame shows that there is no other agent conflict with agent[4] since its initial_position is [21,8].
It is so strange that after I give it a move action, it didnβt depart but remained the state of READY_TO_DEPART(1).
After the blue frame, you can see that I give it more subsequent move actions, but it still didnβt depart but remained the state of READY_TO_DEPART(1).
This strange phenomenon does not happen every time, and I really canβt find the reasonβ¦
I have given the agent a sequence of move action, but it never appear on the map
Almost 3 years agoHere I gave this agent a sequence of actions, but it never appear on the map. And during this period, its initial position is free(no other agent in it).
I think even the actions are wrong, at least, it should appear on the mapβ¦
I donβt know whyβ¦
By the way, I set all speeds 1.0 and didnβt induct malfunction.

Some questions ahout the agents' speed
Almost 3 years agoAbout the first question of this topic, @dipam has answered.
For the second question, my teammate emailed the administer and received the answer as follow:
"So rather than varying speeds itβs clearer to say multiple speeds.
There are different trains with different speeds. Their speeds are fixed throughout and never vary. Some trains are slower some are faster. Unlike round 1 where all were of the same speed.
Let me know if this clarifies your question."
Hope it is helpful to you as well.
Some questions ahout the agents' speed
Almost 3 years agoThanks for your help.
Actually, I still feel puzzled about the βvarying speedsβ at round2. Does it mean that the agentsβ speeds are changeable every step during their traveling and we must check the agentsβ speeds by function βstepβ every step?
The first part of this page makes me confused.
Could you please explain the βvarying speedsβ at round2 in detail? Thanks a lot.
Some questions ahout the agents' speed
Almost 3 years agoI want to consult some questions about the speed of agent.
Firstly, Iβm not sure about if I understand the speed correctly when it is smaller than 1. Assume that the speed of agent[X] is 0.7, and βposition_fractionβ is 0. After 2 steps of moving, does agent[X] reach the next cell and the βposition_fractionβ becomes 0.4?
Secondly, at round 2, the speed is varying. Does it mean that the environment can change the speed and we must check the agentsβ speed by function βstepβ every step?
Is somewhere I can know more details about the speed? Thanks.

Almost 3 years agoSorry, I didnβt pay attention to this part.
So, maybe I canβt help with your debug process.
