the time complexity of algorithms.

Researchers from the School of BioSciences have requested our help with one of their

experiments. They are performing behavioural experiments with zebrafish. At any one instance in

time there are a large number of zebrafish in the aquarium. For their particular experiment, the

biologist take a snapshot of the aquarium and then need to find the longest series of zebrafish such

the length of each fish along the horizontal direction in the aquarium is increasing. They also need

to know the number of zebra fish in this series.

For example, the snapshot of the aquarium resulted in fish lengths of [2, 5, 3, 7, 11, 1, 12, 4, 15, 14, 6, 16].

One possible longest series of increasing lengths in this case is [2, 3, 7, 11, 12, 14, 16] with 7 zebrafish.

We say one possible longest series of increasing lengths here because it is not necessarily unique.

For example, the length 14 in the output could be replaced with 15: [2, 3, 7, 11, 12, 15, 16] and also

be valid.

In this question you will consider algorithms for finding the longest series of increasing lengths

via the function LongestIncreasingLengths(A[0, · · · , n − 1]), as well as the size of this output

array.

(a) [1+2+1 = 4 Marks] Consider a recursive algorithm:

i [1 Mark]Write down a recurrence relation for the function LongestIncreasingLengths.

ii [2 Marks] Using this recurrence relation, write a recursive algorithm in pseudocode for

LongestIncreasingLengths that only calculates the array size of the longest series of

increasing lengths. You do not need to output the actual array containing the longest

series of increasing lengths in this part of the question. For the example above with input

A = [2, 5, 3, 7, 11, 1, 12, 4, 15, 14, 6, 16], the output should just be 7. The pseudocode should

be about 10 lines of code.

iii [1 Mark] What is the time complexity of this recursive algorithm? Justify your answer.

(b) [5+1+1 = 7 Marks]

i [5 Marks] Building on from your recursive algorithm in part (a), write down a dynamic

programming implementation in pseudocode for the function

LongestIncreasingLengths(A[0, · · · , n − 1]) to find the longest series of increasing

lengths. This should also output the size of the longest series of increasing lengths. The

pseudocode should be about 20 lines of code.

ii [1 Mark] Explain how the recurrence relation used for your dynamic programming imple-

mentation involves overlapping instances.

iii [1 Mark] What is the time complexity of your algorithm and how much auxiliary space

was required. Justify your answer.

(c) [1+2 = 3 Marks] The time complexity of the recursive algorithm for LongestIncreasingLengths

was exponential, while the dynamic programming algorithm lead to a polynomial

time complexity (note, you need to determine that polynomial above). Here we will investigate

an algorithm for the function LongestIncreasingLengths that has a time complexity of

O(n log n).

Consider building a set of arrays for the input array A[0, · · · , n − 1]. As we scan along A, we

will compare A[i] with the final element in each array in this set. This comparison will satisfy

the following conditions:

(1) If A[i] is smaller than the final element in each array, start a new array of size 1 with A[i].

(2) If A[i] is larger than the final element in each array, copy the longest array and append

A[i] to this new array.

(3) If A[i] is in between, find the array with the final element that is greater than A[i] and

replace that element with A[i].

i [1 Mark] Write down the set of arrays that satisfy these rules for the input array

A = [0, 8, 4, 12, 2, 10, 6, 14, 1, 9, 5, 13, 3, 11, 7, 15].

ii [2 Marks] Building from these conditions, explain how an algorithm for the function

LongestIncreasingLengths could run with time complexity O(n log n). You may make

use any algorithm introduced in the lectures to help you with your explanation. Note: you

do not have to write this algorithm in pseudocode. We are expecting that you write a short

paragraph or a short list of bullet points describing the important steps of the algorithm

to explain the time complexity.

Hint: what if you only consider the final elements of this set of arrays as a single array?

Digital Forensics Evidence

  

Dwayne and Debbie Tamai Family of Emeryville, Ontario.

Mr. Dwayne Tamai and Mrs. Debbie Tamai case of electronic harassment involved 15-year-old son, Billy, who took control of all of the electronic devices in the family’s home, including the phone, and manipulated them to the distress of other family members for his own amusement. The incidents began in December 1996, when friends of the family complained that phone calls to the Tamai home were repeatedly being waylaid, cut off missed messages, strange clicking and appears like a minor with a disembodied voice, unnervingly distorted by computer, who interrupted calls to make himself known.

After burping repeatedly, the caller frightened Mr. and Mrs. Tamai, and stated that I know who you are, and I stole your voice mail. Mocking, sometimes menacing, the high-tech stalker became a constant presence, eavesdropping on family conversations, switching TV channels, and shutting off the electricity.

The police department confirmed that the sabotage was an inside activity but refrain from releasing the name the culprit. The police further stated that nothing would be gained by filing charges against the suspect. Mr. Dwayne and Mrs. Debbie Tamai asserted that their son, Billy, had admitted engaging in the mysterious calls. The interruptions included burps, blathering and claims having control over the inner workings of the Tamai’s custom-built home, and the power to turn individual appliances on and off via remote control.

It started off as a witticism with friends and got out of control to an extent that he didn’t know how to end the entire operation, become afraid to come forward and tell the parents for the fear of us disowning him.

On Saturday, Mr., and Mrs. Tamai get organized and planned to take their son to the police department to defend him against persistent rumors on him. Instead, Mr., and Mrs. Tamai’s son confessed and labelled an intruder code-named, Sommy. Mr., and Mrs. Tamai eliminated all external sources and had confidence in interior sources. After 2-days, a team of investigators, intelligence and security experts loaded with high-tech equipment failed to locate Sommy. The next day, the team brought in two television networks to assist in the process.

In conclusion, the son, Billy not (Sommy) contacted the victims; (his biological parents), launched verbal threats in combination with the electronic harassment, in an effort to demonstrate his power and authority over them. The best option was, Mr., and Mrs. Tamai victims were not physically harmed, but terrified and greatly inconvenienced by the fact that the unknown force appeared to have control over a great many aspects of their lives, and the unknown force turned out to be their biological son, Billy.

Scenario: 1
Criminal motive is connected to emotional, psychological, and material need are often impel by means of behavior and independent of technology operation. These criminal tendencies are believed to champion the restoration of the criminal’s self-confidence, and self-worth which lead criminals to the path of temporary gratification, inadequacy, and incompetence.
