题意:有n门课程,m天,给一个矩阵,矩阵每个元素 Aij 花 j 天学习i课程可以得到的价值。
思路:DP: now[ia]=max(now[ia],pre[ia−j]+A[i][j]) ,因为 Ai1,Ai2,…,Aim 是相关的,所以要用一个pre数组来存上一门课程处理过后的状态。

利用大规模生物活性挖掘,计算识别针对癌基因驱动蛋白 EGFR、BRAF 与 CDK4 的高亲和力抑制剂 背景:精准癌症治疗需要小分子抑制剂与致瘤蛋白靶点之间的精确匹配。方法:我们使用 Python 及 ChEMBL 数据库 API 开发了一套计算流程,系统性地筛选针对 EGFR、BRAF 与 CDK4 的高亲和力配体。对 IC50 < 1000 nM 的生物活性进行过滤,并检索候选化合物的分子结构(SMILES)以供后续优化。结果:本研究共识别出 [插入总数] 种独特化合物。其中,对 BRAF 激酶而言,我们挑选了一批 IC50 低至 6.0 nM 的高效实验性化合物。 阅读详情
