Cathedral ward (4,217 residents) and Quoile ward (4,172) are census wards at Downpatrick. Lessons follow the Northern Ireland Curriculum year structure used in County Down, and exam support is matched to CCEA specifications. Send us your holiday weeks and lessons will skip them. ### County Down neighbours and CCEA See [Newry](/best-coding-class-in-newry), [Northern Ireland](/coding-and-ai-classes-in-northern-ireland) and [CCEA GCSE Maths help](/ccea-gcse-maths-help). Why thinking comes before tools is explained on [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Downpatrick project ## The smallest circle round every Downpatrick shop: Welzl's algorithm in Python Forty shops, one exact circle, two tempting shortcuts, and a test of what input order does to speed. OpenStreetMap supplies 40 shops inside a rectangle over Downpatrick; where a shop is drawn as an outline, its centre stands in for it. Positions are converted to metres. Welzl's algorithm then builds the smallest enclosing circle: it takes the shops one at a time, and whenever a shop falls outside the current circle, it rebuilds the circle so that this shop sits on its edge. The final circle always rests on two or three points, its support points; every other shop could move a little without changing it. | Method | Radius | Point checks | | --- | --- | --- | | Welzl's algorithm (exact) | 1,834.3 m | 229 | | Try every circle through 2 or 3 shops | 1,834.3 m | 15,409 | | Centre on the middle of the shops' box | 1,855.9 m | Not exact | | Centre on the average shop position | 2,338.7 m | Not exact | Here the tightest circle rests on just two shops, the two farthest apart, and the brute-force search agrees at 1,834.3 m after 15,409 checks against Welzl's 229. The box-centre shortcut happens to come within 22 m, but the average-position shortcut needs a radius 504 m larger, because the average is pulled towards wherever shops cluster: the true centre is 509.4 m away from it. The second experiment uses all 5,865 building centres in the rectangle. With the buildings shuffled, the algorithm needed a median of about 50,200 checks over 20 shuffles. Fed them sorted from west to east, it needed 239,155, and sorted east to west, 205,503. Sorted input keeps putting the next point outside the circle, forcing rebuild after rebuild, which is why the algorithm shuffles first. ### P5 to P7 Pin coins on a map and find the smallest paper circle that covers them all; notice which coins touch the edge. ### Years 8 to 10 Compute the average-centre circle for Downpatrick's shops in Python and measure how much too big it is. ### Year 11 and up Code Welzl's algorithm, count its checks on shuffled and sorted input, and compare with brute force. ### OpenStreetMap places, our circles Shops and buildings are from OpenStreetMap and its contributors under the Open Database Licence. The rectangle, the circles and every count are our own work; shops are not named. Algorithms and AI ## What this teaches about vibe coding and AI agents Correct is not the same as quick; the input decides. | In the geometry project | When AI writes code for you | | --- | --- | | Welzl needed 229 checks, brute force 15,409 | A known algorithm can beat a naive loop by miles | | The average-centre circle was 504 m too wide | An intuitive shortcut can be quietly wrong | | Two shops fixed the whole circle | A few points can decide the answer | | Sorted input took several times the checks | Test code on awkward inputs, not just tidy ones | | Shuffling first protected the speed | Randomness can be a deliberate design choice | Ask an AI assistant for "the smallest circle containing these points" and it may centre a circle on the average and call it done, which our Downpatrick shops show can be 504 m too wide. In vibe coding the learner describes what the program must do and the AI writes the code; our Downpatrick learners then check the result against a brute-force search on a small set and time it on sorted input. AI agents that crunch data for you will not run those checks unless told. We move learners on to agent building once their Python is steady, usually around Year 12 or as adults, and Copilot Studio agents are only taught one-to-one. Two pages say more: [understand the code, don't copy-paste](/understand-the-code-dont-copy-paste-uk), and the [agents route for UK students](/ai-agents-course-for-students-uk). OpenStreetMap and NISRA publish the open data this page relies on and have no link with Modern Age Coders; the circles and any errors in them are ours.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Generative AI Course](/courses/complete-generative-ai-masterclass-college)Python and geometry ## How do you find the smallest circle that contains a set of points? Use Welzl's algorithm: add the points in random order and, whenever one falls outside the current circle, rebuild the circle with that point on its edge; the result rests on just two or three points and takes expected linear time. For Downpatrick's 40 mapped shops it found a 1,834.3 m circle with 229 point checks, where trying every candidate circle took 15,409 and a circle centred on the average shop needed 2,338.7 m. Learners who have run it ask of any code an AI writes: is this the exact answer, and how does it behave on the worst kind of input? A Downpatrick teenager who can test an algorithm on its worst input will not be fooled by code that only works on tidy examples, and Python is where that habit is formed. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## Taught online across County Down A computer, a camera and broadband that can hold a video call are all the equipment required. ### Learner at the keyboard The student writes and runs each step; our tutor follows on screen share and asks them to predict the result first. ### Trial sets the starting topic We see what the learner can already do and note any CCEA course ahead. ### Free opening class The first class is free and finishes with our course recommendation. ### Level-matched groups Classes hold five to ten learners drawn together by stage, not by town. ### Twice weekly in term School holidays off. ### Fixed hour When UK clocks change, our tutors shift so your slot stays the same. Why online Five learners at one level, all free on the same evening, rarely live close together. Video makes the distance irrelevant. Fees ## Downpatrick fees Learners in Downpatrick pay our international rates, applied in every country except India. First class**USD 0** One complete free lesson, then a suggestion. Group tuition**USD 100** Roughly eight live group lessons monthly. Private tuition**USD 150** Roughly eight live one-to-one lessons monthly. Downpatrick families see prices in US dollars only. Nothing is invoiced until after the trial, once a course and a regular slot are fixed; the pricing page handles breaks, missed sessions and format changes.

FAQ ## Downpatrick questions Enclosing circles, the shop project, Python, vibe coding and practical points. ### What is the population of Downpatrick? NISRA's Census 2021 counts 11,545 usual residents in the Downpatrick settlement and 21,916 in the Downpatrick district electoral area. ### Are online Python classes available in Downpatrick? You can: lessons run over live video, so anyone 6 to 67 in Killyleagh, Ardglass or elsewhere in the district can join. ### What is Welzl's algorithm? A randomised method for finding the smallest circle around a set of points. It adds points one at a time and rebuilds the circle only when a point falls outside, running in expected linear time. ### Why does input order matter for a randomised algorithm? Its speed guarantee assumes random order. On sorted input, each new point tends to fall outside the circle, forcing repeated rebuilds; in our test, sorted building data took about four to five times as many checks as a typical shuffle. ### What does the Downpatrick project involve? Finding the smallest circle round 40 mapped Downpatrick shops with Welzl's algorithm, comparing it with shortcuts and brute force, and timing it on 5,865 buildings in different orders. ### Is vibe coding included? It is, for all ages: the learner sets out what the program must do, then checks and corrects what the AI writes. ### When can learners build AI agents? Once Python feels natural, which is usually from Year 12 or in adulthood; Copilot Studio needs private lessons. ### Which CCEA subjects can you help with? Yes, in Maths, Digital Technology and Software Systems Development, taught for understanding with no promised grades. ### What do lessons cost? Free for the trial; afterwards USD 100 monthly as part of a class, USD 150 monthly one-to-one. ### Are lessons paused for holidays? Yes, for school holidays; send the dates.
