В общем, была задача на оптимизацию плана работ: есть набор заказов, и в каждом N тасков. Таски могут зависеть друг от друга или нет, имеют длительность и тип. Ещё есть M работников, каждый из которых может выполнять таски только определённых типов, причём, у каждого своя скорость. Если все таски в заказе выполнены, фирма получает сколько-то денег. У заказа есть дедлайн, за просрочку штраф (за каждый день просрочки), который вычитается из цены заказа. И ещё фирма тратит деньги за каждый день своей работы независимо от того, как загружены её сотрудники (то есть просто платит зарплаты по сути). Ещё важен учёт праздников и выходных. Нужно заработать на определённом наборе заказов и работников как можно больше денег. Полный текст задачи и код программы проверки есть в репозитории. Эта задача является изменённым заказом, который мы с напарником решали в реальной жизни: оптимизация работы печатных станков для типографии. Правда, тогда и мы справились так себе, и заказчик в итоге сначала захотел всё вручную сам делать, а потом и вовсе похоронил проект при смене директора. !!! Не читайте дальше, если хотите сначала попробовать решить самостоятельно, потому что я сейчас опишу эффективные подходы и результаты. ________________________________________ Так вот. Мы с другим экспертом Андреем сразу сели и написали разные варианты, чтобы задать шкалу, по которой будем оценивать решения команд. За пару часов я собрал примитивный жадный алгоритм, который сортировал заказы по прибыльности и укладывал в сетку кое-как, это дало нам нижнюю оценку. Мой алгоритм заработал ~75 млн виртуальных рублей, мы решили для оценки поставить нижней границей 40 млн. То есть всё, что ещё ниже, оценивалось в ноль баллов за качество оптимизации. Затем Андрей закрылся дома на три дня и вышел на свет со сложным жадным алгоритмом, который очень хитро сортировал заказы и очень хитро укладывал их в сетку, попутно выбирая разные способы этой укладки в зависимости от конкретного заказа. Это позволило заработать ~275 млн рублей. Мы сделали верхней границей для оценки 280 млн. К сожалению, в итоге только две команды из десяти прошли нижнюю границу, заработав, соответственно, ~91 и ~105 млн. К верхней границе не приблизился никто. И у четырёх команд алгоритм вообще не смог уложить без нарушений задачи в сетку (то есть, например, произвольно менял длительности, накладывал задачи друг на друга, давал одному работнику две задачи в один момент и так далее). Важной ошибкой команд, на мой взгляд, являлся тот факт, что никто не воспользовался возможностью запустить алгоритм на несколько минут и дать ему поработать. По условиям задания, можно было тянуть до 5 минут на одну оптимизацию, но по факту решения команд отрабатывали за единицы и десятки секунд. На самом конкурсе, пока команды работали, я решил попробовать сделать быстрое (по времени написания) но эффективное решение. Сначала попробовал жадную сортировку + доведение до лучшего варианта методом имитации отжига. В качестве нового состояния я просто менял местами заказы целиком. Этот вариант работал пару минут и дал мне около ~200 млн дохода. К слову, команда-лидер использовала такой же подход, просто не докрутила число итераций и температуру. Ну и потом я взял готовую либу по реализации классической генетики с особями и скрещиванием. Особью был массив с приоритетами заказов (которые конечно же нужно было аккуратно уложить чистым алгоритмом). Тип скрещивания: scattered. Всего 15 поколений по 20 особей, и это за минуту-полторы давало ~230-240 млн. Считаю, что для конкурса это самый лучший выбор: пишется одним человеком за день и даёт почти максимум, при этом легко настраивается на нужную длительность работы, легко параллелится. Ну а потом уже дома я посидел и накодил свой вариант сложного жадного с плавающим окном перебора отсортированных заказов и плавающей же укладкой по работникам. Такая штука за две минуты зарабатывает ~281 млн. Но за три дня в условиях стресса я бы такое не сделал, скорее всего. #dev

📣 Pump result : The pump didn't go as we expected, and for that, we deeply regret any disappointment caused to our community. This time our efforts led to a peak of 100% profit. While this is a positive result, it's not up to the high standards we set for ourselves and for you. We encountered an "iceberg" coin, presenting us with unexpected and relentless sell orders, which significantly impacted our strategy. In addition, we faced external challenges with large on-chain OTC transactions to kucoin accounts creating sell walls below our targets, quickly affecting the coin's momentum. We chose this coin based on its potential for a potential ATH breakout, doing so would've lured thousands of traders to trade the dips alongside our community, aiming to maximize your profits. Unfortunately, this decision didn't yield the results we expected. Our team has tried to keep the price up but was unsuccessful due to the nature of this coin. We invite everyone to take a look at the daily chart to understand more our reasoning behind this pick. Our team had the pure intention of boosting the price up to at least 2000% in this pump for all our members but unfortunately it was impossible on this coin. In the next pump we will make sure we pick a coin that we know for sure can be pumped to more than 1000%+ and our team will make sure that we will reach that target once again by injecting a massive amount of USDT during the pump after our members had bought already. Our whales will use our own capital to push a coin similar to the mega pump which took place on #QUICK, with that being said we expect another 1000%+ profit signal. Today was a one off result, the amount of factors which could've gone into play today were immeasurable and we apologize once again for the lack of foresight. Next pump we will absolutely make sure that we pick a coin we have experience in and that can definitely be pumped to a high price without facing any issue. Stay tuned for our next announcement!

Pump result : One of the best pumps we have had lately! The volume was around 2 million $ with a peak of almost 1500% exactly 6 minutes after the signal was given which is very impressive. The signal on #QUICK was announced and the price started to steadily rise 400%, and with the help of our whales and our big influence the price managed to climb to a whopping 1500% just a few minutes later meaning that everyone that had bought within the first 7 minutes made a massive amount of profits. There were several waves to profit from during the pump, and we're glad to hear so many of you managed to earn alot today. #QUICK is still sitting at over 500% over an hour later, we promised you guys a special pump to end this year off and we did exactly that! Our signals will keep getting better because our community is growing massively! With our current calculations we are expecting at least 100k new members by the start of the next pump which we will try to surpass a 2000% profit target. Our power is starting to get uncontrollably huge and we thank you guys for trusting us all this time, we appreciate each and everyone of you and hope you and will continue to do what we do best. Stay tuned for the next one as it is going to be even bigger. Our team will make sure to deliver the biggest pumps we have ever seen starting in 2024. Happy holidays everyone.

Love & Relationship Tips ❤ 💖

💥HOW TO WIN YOUR CRUSH 💥 Part 4 📌 Be flirtatious One of the easiest ways to let him know you’re interested is by flirting. Though this may not be the initial approach you want to take in your texts, once you feel comfortable flirting with him, make sure you do so in a fun, exciting way—without giving away your feelings too much. The trick is to not make him think that you’re crazy about him, because you don’t want to overwhelm him or make him feel smothered. Finding the right balance will have him feeling excited to talk to you and curious about your feelings for him. He’ll also be impressed by your confidence. An easy way to flirt with someone without coming off too strong is by teasing them. Again, be careful not to take this overboard or he may start to consider you as “one of the guys”. Use winking emoticons and make cute innuendos to let him know that you’re excited to see him or to hint that things may get hot and steamy when you do. #Quick Tip: If you already have a texting relationship, sending a sweet text saying, “Hope you’re having a great day!” or, “Thinking of you :)” will cheer him up and keep you on his mind. Since most guys have a positive reaction to the word “great” it’s a helpful word to use. More on this later.
