Language
Evaluating Solutions
language shapes thoughts
enables communication
affects how we view a problem
and what tools we can use to solve it
domain specific language
learn it
abandon preconceptions
focus on how is used in text
domain specific language
look for domain specific websites and publications to learn
domain specific language
look at professional/trade organizations

Evaluating Solutions
so, you have a solution
is it any good?
is it the best?
what does that even mean?
lets find out
P a r t 1:
F o r m a l
Fogler & LeBlanc
clearly state problem
needs
wants
assign weights
assign values
compare
reflect
example:
decide on where to eat
Activity
Create a list of needs and wants for a solution
to: I need to get to my next class in Luddy.
Activity
Don't forget to assign weights
P a r t 2:
I n f o r m a l
pause
reflect
explicitly explore multiple possibilities
Metacognition
check if answer makes sense
Metacognition
does your answer form a complete thought in and of itself?
distance
go through all stated goal one at a time
does your solution meet each one?
if partial, to what degree?
compare with other possible solutions
what are the costs?
what are the side effects?
implementation
reception
upsides?
explicitly compare cost/benefit
feasibility
reliability
relation to existing solutions
novelty
coherency
unity
refinement
aesthetics
review your review
reevaluate criteria
follow up with implementation
P a r t 3:
R e a s o n a b l e n e s s
Reasonableness
reread
Reasonableness
rewrite individual problem pieces
Reasonableness
define the question
Reasonableness
is it possible
Reasonableness
is it sensible
Reasonableness
estimate solution
Reasonableness
nearest order estimation
Reasonableness
ranges
Reasonableness
say your solution
Reasonableness
imagine your solution in action
Reasonableness
rephrase your solution
P a r t 4:
M e t a c o g n i t i o n
Metacognition
why am i thinking this way
Metacognition
are there other alternatives to explore?
Metacognition
record thoughts and process explicitly
Metacognition
review
Metacognition
share
Activity
HPC job scheduler
Go to website http://cgi.sice.indiana.edu/~dpierz/hpc/hpcgame/scheduler.html
These frames represent 3 nodes, each with different properties.
Confer with your team to place pieces inside your frame to represent jobs being packed onto nodes.
Pieces must fit entirely inside the frame. In 4 hours, we’re shutting down the server.
The pieces have a specific orientation – no rotating or folding!
CPUS
Time (hours)
Pieces are color-coded by the user that submitted them. They may take various lengths of time, require various numbers of cpus, and may have other requirements (like large memory – we only give you one such piece).
