15804527069	Algorithm	a step-by-step set of instructions implemented by a program to develop and express solutions to a computational problem	0
15804527070	Sequencing	ordering the steps of an algorithm; one of three different types of algorithms	1
15804527071	Boolean condition	a decision in an algorithm based on either true or false	2
15804527072	Selection	using a condition to to control the logical path taken by an algorithm; one of three different types of algorithms	3
15804527073	Iteration	a loop or repeated behavior in an algorithm; one of the three different types of algorithms	4
15804527074	Pseudo code	words used to organize thoughts to help plan writing code; helps programmers translate specifications into code	5
15804527075	Natural language	a human language such as English, Spanish, German, etc.; as opposed to artificial terms used in programming languages	6
15804527076	Run Time	the period during which a computer program is executing	7
15804527077	Reasonable time	a way to analyze an algorithm in terms of the number of steps required to solve a problem; an algorithm is given this designation if the number of steps the algorithm takes is less than or equal to a polynomial function of the size of the set.	8
15804527078	Solvable problem	a problem that can be solved exactly using an algorithm	9
15804527079	Unsolvable problem	a problem that cannot be solved exactly using an algorithm	10
15804527080	Heuristic solution	algorithmic approach applied to improve an algorithm that is based on finding solutions among all available options using a general set of rules; may result in approximate solutions instead of exact solutions; may be helpful to find solutions in reasonable time; may be helpful to find approximate solutions to unsolvable problems	11
15804527081	Undecidable problem	problem in which no algorithms can be constructed to answer "yes" or "no" for all inputs	12
15804527082	Decidable problem	problem in which an algorithm can be constructed to answer "yes" or "no" for all inputs	13
15804527083	Empirical analysis	an evidence-based approach to the study and interpretation of information	14
15804527084	Linear search	a search algorithm that finds a target by looking at each item, one at a time, until the end of the set is reached or the target is found	15
15804527085	Binary search	a search algorithm that finds a target in a sorted list by starting in the middle. If the target is less than than the middle term, the algorithm then looks at the middle of the lower half. The process of narrowing the search by halves continues until the target is found or until it is determined that the target does not exist in the list.	16
