Assignment
10 Marks
Part-1
Dear Student, you may have heard
about ELIZA program…which was originally developed by Joseph
Weizenbaum in 1964-66 at MIT. Later on, lots of improvements have been made
and different versions have been released. Attached with this assignment
is an enhanced ELIZA program. This
program pretends to be a Psychotherapist and can engage you in a
serious conversation. Your task is just to run this program, have some
discussion for fun on any topic of your interest. I hope you will appreciate
its intelligent responses.
You need to submit two snapshots of your discussion with this program,
- In the first snapshot: you must mention your name and VU-ID and that shall be highlighted in your snapshot.
- In the second snapshot: you can submit any part of the discussion which you like the most.
Note:
- You will need DOSBox software for using Eliza program on 64-bit Windows 7. DOSBox is available on LMS download section.
- Sample of desired screen shots are shown on Page 4… see Figure-1 and Figure-2.

Part-2
In early chapters (Lecture No. 5),
you have studied and practiced that how Two-One problem was solved
systemically which might have appeared to most of you very hard at first
instant. In this part you are given a very interesting problem situation and
you need to devise some intelligent mechanism to find its solution. I name this
problem as 3 or 13-problem.
3 or 13 Problem: Consider
a shopkeeper who is running a sugar store in a town ABC where people
used to buy sugar in kilograms. Orders of people of the town ranges from 1Kg to
13Kg and the shopkeeper wants to weight the desired demand in one go. For this
purpose, the shopkeeper has kept 13 stones, weighing from 1Kg to 13Kg and they
are labeled and placed properly in one corner of his shop… now for example a
customer order N Kg of sugar (where N must be in range 1 - 13), shopkeeper
simply picks the stone weighing N Kg and deliver the desired demand in one go.
One day a Wiseman came, and
advised the shopkeeper to keep only 3 stones and throw away the remaining 10
stones as they have occupied too much space. Shopkeeper can still weight orders
from 1-13 Kg in one go with those selected 3 stones…by placing one or more
stones in either pan of the Balance.
Your task is to find, which 3
stones were suggested by the Wiseman? Note: your selected 3 stones must fulfill
the shopkeeper demand i.e. to weight sugar from 1Kg to 13Kg in one go. One or
more stones can be kept in either pan of the Balance to get the desired weight.
You must complete the following table…provide pan status of the Balance for
each desired weight with your selected 3 stones.

Submission
You are required to submit your solution in MS Word format
through LMS.
§
Answer to part requires two screen shots of your
discussion with Eliza program as desired.

Complete the above table showing pan status for
each desired weight with your selected 3 stones.

Let say I selected 3 stones as

Stone 2 = 4KG
Stone 3 = 6KG

As you can see, I am unable to
get correct pan configuration for weighing 8KG, 11KG and 12KG in one go…that’s
why my selected 3 stones is not the required correct solution.
Only that solution will be
considered as correct if it can weigh ALL required weights (1KG to 13KG) in one
go.
You can
be the Wiseman if you are able to figure out those desired 3 stones
