Postcodes.io lists Academy, Ardeevin, Ballee and Harryville, Ballykeel, Braidwater, Castle Demesne, Fair Green, Galgorm, Kirkinriola and Park among the electoral wards of BT42 and BT43, districts that also take in Ahoghill, Broughshane and Cullybackey. Lessons follow the Northern Ireland Curriculum from P1 to Year 14, with CCEA GCSE and A level support in Digital Technology, Computer Science and Maths; send the holiday dates and we will work round them. ### Mid and East Antrim and Northern Ireland See [coding classes in Mid and East Antrim](/coding-classes-in-mid-and-east-antrim) and the [Northern Ireland page](/coding-and-ai-classes-in-northern-ireland). Why we teach problem solving before tools is on [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Ballymena project ## Greedy against exact: an integer programming puzzle on Ballymena's map Fewest junctions, every building within 400 m, three ways to answer, and a proof of how good an answer can be. The learner downloads OpenStreetMap data over Ballymena and finds 2,473 street junctions where three or more roads meet, and 11,552 buildings. For each building Python lists every junction within 400 m in a straight line; 11,534 buildings have at least one, and the 18 that do not are set aside. The puzzle is a classic called set cover: choose as few junctions as possible so that every remaining building has a chosen junction within 400 m. It is a thought experiment about coverage, the same shape as siting bins or chargers, not a plan for anything real. | Method | Junctions needed | What it tells you | | --- | --- | --- | | Greedy rule | 69 | A good answer in about a second | | LP relaxation (HiGHS) | 48.27 | No answer can use fewer than 49 | | Integer programming (scipy milp, 10-minute limit) | 50 | Smallest cover found; the true minimum is 49 or 50 | The greedy rule, always taking the junction that covers the most still-uncovered buildings, finishes almost instantly with 69. The solver, scipy's milp using the HiGHS engine, searches much harder and finds a cover of 50. The LP relaxation, the same problem with the rule "each junction is fully chosen or not" loosened to allow fractions, has a smallest total of 48.27, and since a real answer must be a whole number of junctions, nothing below 49 is possible. So the greedy answer uses 19 or 20 more junctions than necessary, roughly 40% extra, and we can say that with certainty without ever finding the exact optimum. ### P5 to P7 Place counters on a grid so every square is next to one, first quickly, then with the fewest you can manage. ### Years 8 to 10 Write the greedy rule in Python for a small patch of Ballymena and count the junctions it picks. ### Years 11 and up Set up the integer program with scipy, solve it, and use the LP relaxation to prove a lower bound. ### OpenStreetMap data, our puzzle Buildings and streets are from OpenStreetMap and its contributors under the Open Database Licence. The junction list, distances, puzzle and every result are our own work; straight-line distances ignore walls, rivers and roads. Answers and AI ## What this teaches about vibe coding and AI agents Speed is worth having only when you also know the size of the shortfall. | In the optimisation project | When AI solves a problem for you | | --- | --- | | Greedy gave 69 in a second | Quick heuristics are often what an AI writes | | The solver found 50 | A better method can cut the cost a lot | | The relaxation proved at least 49 | Bounds tell you how good an answer is | | The exact optimum stayed unproven | Some certainty is enough to decide | | 18 buildings could not be covered | Check which cases a method silently drops | Ask an AI assistant for code to "pick the fewest locations" and you will very often get a greedy loop, which runs and looks convincing. In vibe coding the learner describes the program and the AI writes it; our Ballymena learners then ask how far the answer could be from the optimum, and compute a bound to find out. AI agents that make choices with real costs, scheduling people or placing resources, should report that kind of gap too. Agent building comes after a learner can write Python without support, commonly in the sixth form or as an adult, and Copilot Studio agents are kept to private lessons. The pathway is described on [agents for UK students](/ai-agents-course-for-students-uk); the thinking behind it on [understand the code, don't copy-paste](/understand-the-code-dont-copy-paste-uk). The data behind this page is open data from OpenStreetMap, NISRA and postcodes.io, none of whom is linked to us; the puzzle, the code and any slip are Modern Age Coders' own. Stages ## From counter puzzles to integer programs A school year gives a starting guess; the free lesson pins it down.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Generative AI Course](/courses/complete-generative-ai-masterclass-college)Python and optimisation ## What is integer programming, and how can Python tell you how good a greedy answer is? Integer programming finds optimal whole-number choices under constraints, and its LP relaxation, the same problem with fractions allowed, gives a lower bound that shows how far any quick greedy answer could be from the optimum. On a coverage puzzle over 11,552 mapped Ballymena buildings, a greedy rule needed 69 junctions, an integer programming solver in Python found 50, and the LP relaxation proved that no answer could use fewer than 49. Learners who have solved it ask of any AI-written heuristic: how far from optimal could this be, and can we bound it? Knowing how to check a quick answer keeps Ballymena teenagers in charge of AI-written code, a solid reason to learn Python in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## Galgorm to Harryville, online Any computer with a webcam and a connection good enough for video will do. ### Learner at the keyboard Every line and prompt is typed by the student, and the tutor, watching on screen share, keeps asking whether a cheaper answer exists. ### Where to begin Worked out in the trial, and any CCEA exam goes straight into the plan. ### Taster at no cost We teach a full opening session for free and recommend a course afterwards. ### Classes by ability A group means five to ten learners working at one level, from all over the UK. ### Twice a week Paused for school holidays. ### Steady time Our tutors adjust for UK clock changes, so your slot stays the same. Why online Five learners at one level, free on the same evening and living near each other, are hard to find. Online, they need not be neighbours. Fees ## Ballymena fees Ballymena learners pay our international prices, the rates for every country except India. First class**USD 0** One whole lesson free, then our advice. Group tuition**USD 100** Roughly eight live group lessons each month. Private tuition**USD 150** Roughly eight live private lessons each month. Ballymena families pay in US dollars, with no sterling list, from the point the trial has agreed a course and a time. Holiday breaks, missed sessions and format swaps are all laid out on the pricing page.

FAQ ## Ballymena questions Solvers, bounds, the Ballymena puzzle, vibe coding and lesson arrangements. ### What is the population of Ballymena? NISRA counted 31,205 usual residents in the Ballymena settlement at the 2021 census. ### Are online Python classes available in Ballymena? Classes run over live video, so learners aged 6 to 67 in Ahoghill, Broughshane or anywhere else in Mid and East Antrim can join. ### What is the set cover problem? Choosing the smallest collection of options that together cover every item. In our Ballymena puzzle the options are junctions and the items are buildings within 400 m. ### What is an LP relaxation? The same optimisation with whole-number choices loosened to fractions. It is quick to solve and gives a bound: here 48.27, so no cover can use fewer than 49 junctions. ### What does the Ballymena project involve? Setting a coverage puzzle on OpenStreetMap buildings and junctions, then solving it greedily, exactly with scipy's milp solver, and by LP relaxation to measure the gap. ### Is vibe coding taught? Yes, at every age; learners describe the program, then test and correct what the AI writes. ### When do learners build AI agents? When a learner can build small Python tools unaided, typically sixth-form age or older; Copilot Studio is private-only. ### Do you support CCEA GCSE and A level? Yes, in Digital Technology, Computer Science and Maths, taught for understanding without promised grades. ### How much are the classes? We charge nothing for the taster. Regular classes are USD 100 per month grouped, or USD 150 per month individually. ### Do lessons pause in the holidays? They stop for school holidays; share the dates and we plan round them.
