My name is Craig Daniels

I am a graduate student in Mathematics in 
Portland State University and a T.A. for this course

This is an answer to intermediate 
problem one from unit five

What we want to do is to create some 
sliders to replace some of the global

variables that have been set

so, if we click on "code" and the go to 
"find" -this is our "Mac" (Macintosh)

I wanna start looking for code that has
"wall-penalty" so, type that in

so we go through there where 
we have some global variables

we can see we also set it and..

then there's some code that uses it, this
is down at the bottom of the screen

and more code that uses it, so browsing the 
code here we come back to the global setup

so, we need to comment it out
in two places, do that here

there's a semi-colon for it -comment,

and I'm gonna -kinda, paste it so 
that, so that it's still

there if I wanted to get to it later

take it out there and then also, we 
are going to set it with the slider

this is so it'll be easier to comment out

now, we remove the setup and 
the declaration of the global

and now we need to make
a slider to replace it

so we take a slider, and let's say, here..

and then..

we're replacing "wall-penalty"

and I think we start with the 
value "five" because it's what

the program has used

so now we got that; now..

we'll just check and 
see if the code would run

because it always a great
thing to do after each change

-that I..

I'll take out a few updates 
so it goes faster

there! it's running!

so, now we're gonna stop;

here's the "Halt"

let's go ahead and do 
all that together now

now we're going to do a "Find" again

with like "command" + "F"

let's do "can-reward"

alright, now we're also gonna do 
a number of runs for fitness and

and number of actions per environment

so..

we can actually find at
this point now that

we can comment all this stuff out 
without having to search through again

I'm gonna clean that up a little bit

and here are the other.. two..

so these are five things now

Great! it should tell us
that we got some problems

which is fine -we know that;

we're gonna go ahead and 
create the rest of the sliders

alright, this one is going
to be for "can-reward"

and -I guess, I'll make them 
all five for starting..

this isn't the prettiest or the 
nicest place to put all these things..

alright..

now we're gonna add slider 
fitness, we're gonna do that next..

and finally, "number 
of actions per environment"

OK..

At this point..

Ok, so what happened there?

so we made a mistake then!

I think I pre-word

many of you probably have 
noticed that while I was working on it!

alright!

now, let's see..

we've got everything I see in our 
build you can see the slider, you can now..

set them to whatever you would like

so I'll set it up!

still running past her

go in generation

and it seems to be working

so, at this point you can 
experiment with that

and you can also

move the items in the

interface around a little bit so it looks prettier..
