This optimization\nalgorithm fuses the robustness of the population-based global\noptimization algorithm \"Differential Evolution\" with the\nefficiency of gradient-based optimization. The derivative-free\nalgorithm uses population members to build stochastic gradient\nestimates, without any additional objective function\nevaluations. Sala, Baldanzini, and Pierini argue this algorithm\nis useful for 'difficult optimization problems under a tight\nfunction evaluation budget.' This package can run SQG-DE in\nparallel and sequentially.", "License": "MIT + file LICENSE", "URL": "https://github.com/bmgaldo/graDiEnt", "BugReports": "https://github.com/bmgaldo/graDiEnt", "Encoding": "UTF-8", "RoxygenNote": "7.3.2", "Repository": "https://bmgaldo.r-universe.dev", "Date/Publication": "2026-05-15 22:33:15 UTC", "RemoteUrl": "https://github.com/bmgaldo/gradient", "RemoteRef": "HEAD", "RemoteSha": "fd8f83eb6e382e104fbfb803c0f86fea89aa08e5", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-15 22:57:48 UTC", "User": "root" }, "Author": "Brendan Matthew Galdo [aut, cre] (ORCID:\n)", "Maintainer": "Brendan Matthew Galdo ", "MD5sum": "cf88273b3f172a40101553a3122ae0bd", "_user": "bmgaldo", "_type": "src", "_file": "graDiEnt_1.1.0.tar.gz", "_fileid": "a3e652cd97afb1193fd246e4b08b7090a07e4f77ce4a445d6d4b21d9485c3005", "_filesize": 115854, "_sha256": "a3e652cd97afb1193fd246e4b08b7090a07e4f77ce4a445d6d4b21d9485c3005", "_created": "2026-05-15T22:57:48.000Z", "_published": "2026-06-02T19:05:10.957Z", "_distro": "noble", "_jobs": [ { "job": 79150379435, "time": 106, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "7028020826" }, { "job": 79150379518, "time": 106, "config": "linux-release-x86_64", "r": "4.6.0", "check": "OK", "artifact": "7028020911" }, { "job": 79150379500, "time": 81, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "7028016219" }, { "job": 79150379579, "time": 91, "config": "macos-release-arm64", "r": "4.6.0", "check": "OK", "artifact": "7028018228" }, { "job": 79150378504, "time": 155, "config": "source", "r": "4.6.0", "check": "OK", "artifact": "7028001208" }, { "job": 79150378674, "time": 74, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "7367256611" }, { "job": 79150379679, "time": 76, "config": "windows-devel", "r": "4.7.0", "check": "OK", "artifact": "7028015121" }, { "job": 79150379526, "time": 65, "config": "windows-oldrel", "r": "4.5.3", "check": "OK", "artifact": "7028013065" }, { "job": 79150379229, "time": 73, "config": "windows-release", "r": "4.6.0", "check": "OK", "artifact": "7028014632" } ], "_buildurl": "https://github.com/r-universe/bmgaldo/actions/runs/25945274587", "_status": "success", "_host": "GitHub-Actions", "_upstream": "https://github.com/bmgaldo/gradient", "_commit": { "id": "fd8f83eb6e382e104fbfb803c0f86fea89aa08e5", "author": "Brendan Matthew Galdo ", "committer": "GitHub ", "message": "Merge pull request #17 from bmgaldo/improve-algo-params-tests\n\nblock coordinate updating", "time": 1778884395 }, "_maintainer": { "name": "Brendan Matthew Galdo", "email": "brendan.m.galdo@gmail.com", "login": "bmgaldo", "uuid": 22782801, "orcid": "0000-0002-1279-3859" }, "_registered": true, "_dependencies": [ { "package": "R", "version": ">= 3.5.0", "role": "Depends" }, { "package": "stats", "role": "Imports" }, { "package": "parallel", "role": "Imports" }, { "package": "testthat", "version": ">= 3.0.0", "role": "Suggests" } ], "_owner": "bmgaldo", "_selfowned": true, "_usedby": 0, "_updates": [ { "week": "2026-19", "n": 7 }, { "week": "2026-20", "n": 3 } ], "_tags": [], "_stars": 4, "_contributors": [ { "user": "bmgaldo", "count": 58, "uuid": 22782801 }, { "user": "noahmthomas-nmt", "count": 2, "uuid": 58856821 } ], "_userbio": { "uuid": 22782801, "type": "user", "name": "Brendan Matthew Galdo", "description": "Data scientist.
